Best Seamless Underwear That Feel Like Second Skin

Panties, as we know them, were designed back when women always wore slips under their clothes. Today, we wear a lot of knits that cling to our bodies and show exactly if we prefer thongs or briefs.

It's time to rethink our underwear. It's time to go seamless.

Seamless underwear has been around for a while, but it was mostly the worst kept secret of ballet dancers and Hollywood celebrities. It's not that we couldn't get out hands on a pair, it's just that we thought we need those lacy little nothings instead.

Well, no more. If you are going to slip into that bodycon dress or your favorite pair of leggings, let's make panty lines a thing of the past.

Our Requirements

We understand that a single model of panties will not work for everyone. We have our top pick and we use it as the benchmark because it fulfills most of our requirements.

Most is not all, so we are also looking for panties that fulfill specific needs. They need to be well-designed, made from good materials, and better than all other models in their sub-category.

Each pair needs to be durable and easy to maintain. And we are definitely avoiding stupid designs like large tags or impractical decorations. Extra points for a good color palette. of neutrals and brights. The sizes range from XS to XL.

Best Overall: Calvin Klein Invisibles Hipster

Pros

  • Super-smooth with clean edges.
  • No tags.
  • High-quality materials and construction.

Con

  • Sizes run small.

Calvin Klein knows how to do underwear and they are proving that again with this seamless model. They are the most comfortable pair of panties we have all tried and are truly suitable for any season or activity. And they feel so amazing against the skin, it made us all feel like CK models.

They are made of mostly good-quality nylon with some elastane that proved very durable. You have your pick of color with a very generous palette of neutrals

Best Budget: Fruit of the Loom Seamless Panties

Pros

  • Comfortable and breathable.
  • True to size and a good size range.
  • Smooth leg opening and waistband fit.

Con

  • Short lifespan.

Fruit of the Loom slides onto this list with a pack of underwear for the same price as a single pair from other brands. They come in four styles - bikini, high-cut, hipster, and low-rise briefs. Each pack is color coordinated and truly delivers maximum bang for your buck. It's just that you're getting what you pay for. They're great for experimenting with this style before you invest in something of better quality.

They are made completely from nylon and they come in 6 and 8-pack of mostly neutrals, pinks, and purples. They offer both straight and plus sizes.

Best Value: Commando Butter High Rise Panty

Pros

  • Pilling resistant.
  • High recovery.
  • Amazing quality for the price.

What We Don't Like

  • Have to be washed in cold water.

For some of us, this con is not that much of a problem since we're used to wash all our clothes in cold water. For the others, it's just a no-go since we need the heat when washing undies. You will have to decide where you fall. Other than that, these Commando panties are well-made, perform well in both everyday and high-intensity physical situations, and have proven to have great longevity.

They are composed of mostly modal with some elastane. The shade range is limited only to Sand and Black, and the sizes range from XS to XL.

Best Briefs: Spanx Undie-tectable Brief

Pros

  • Subtle shaping effect.
  • Lightweight and breathable.
  • Very undetectable.

Con

  • Short lifespan.

This is one of the best pairs of briefs we have ever tried. And since it's Spanx, they do some wonderful things to our tummies and tushies. They are also completely invisible under leggings and summer dresses. That makes it even more unfortunate that their lifespan can be very short. We had some luck in keeping them in good shape when washing in cold water, but we still hope that the brand will come up with an upgrade.

The material is a combo of nylon and elastane and they come in a rich palette of shades and a few prints. The sizes range from XS to XL.

Best High-Waisted: CUUP The Tap

Pros

  • High-quality materials and construction.
  • Perfect coverage.
  • Great color palette.

Con

  • May stretch out too quickly.

This offering from CUUP is made from a mesh material. It's supposed to be breathable and allow for a sew-free finish. Though this allows them to be truly invisible and comfortable, this means the mesh may stretch out faster than more traditional fabrics. You will have to make sure to wash these panties in cold water to prevent that from happening.

The Tap is available in both modal and polyamide models. The color palette features both neutral and bright shades, and the sizes range from XS to XXL.

Best High-Waisted Hipster: Intimissimi Invisible Touch Hipster

Pros

  • Fully seamless design.
  • Almost feels like nothing on the skin.
  • A good selection of nude shades.

Con

  • Sizes range only from S to L.

These are the true definition of invisible underwear. They feel like they are not even there. They don't appear even under satin or low0quality leggings. And the palette covers a decent range of nudes. They would have been our top pick if the size range was not so underwhelming.

They are made from a blend of polyamide and elastane, with a 100% cotton gusset. Beside nudes and neutrals, the line offers a couple of lovely pastel shades.

Best Compression Thong: Commando Classic Control Thong

Pros

  • Anti-pilling.
  • Washing machine and dryer safe.
  • Moisture-wicking and fast-drying.

Con

  • Fit is not suitable for all body types.

If you prefer wearing thongs but still want some tummy support, then the Commando Classic Control Thong is for you. It offers a moderate amount of compression without making you feel stuffed. The raw edges of the leg opening don't dig into the skin and the band lays completely flat.

Best Cheeky: Aerie No Show Cheeky Underwear

Pros

  • Affordable.
  • Moisture-wicking.
  • Fun colors and prints.

Con

  • They may move during wear.

The Aerie No Shor Cheekies are the best fit for those who love low-rise jeans and brightly colored underwear. If you want to collect them all, the brand offers one of those "buy 10" deals on top of a very affordable price. Though they shift a bit during wear, it's not noticeable under most of the clothes.

The cut fits all body types, and the sizes range from XXS to XXL. They are made mostly from spandex and are suitable for both everyday wear and exercise.

They are made from fully recycled nylon and spandex. The color palette is neutral and includes black and a couple of nude options. The sizes range from XS to XL.

Best for Postpartum: HATCH Seamless Belly Brief

Pros

  • Comfortable all-day support.
  • Compression with light sculpting effect.
  • Smart and functional design.

Con

  • Available only in Sand and Black.

These are godsent for any new mom. They provide subtle shaping and compression without putting your body under necessary stress. Every aspect is designed to provide comfort and aid in recovery. And they still manage not to look like granny panties.

The are mostly made out of modal with some spandex and elastane. The sizes range from S to XL, and the manufacturer recommends measuring the widest part of your hips when picking the size.

Best High-Rise Boyshort: Lunya Soft Supportive Seamless Modal Boyshort

Pros

  • Slight lifting effect.
  • Perfect amount of stretch.
  • Prevents chafing.

What We Don't Like

  • Sizes run small.

The Lunya Soft Supportive Seamless Modal Boyshort is a great pick for everyday wear, but especially with your favorite pair of leggings or skinny jeans. They don't quite lift and sculpt like proper shapewear, but they will provide some extra support and perkiness. Plus the lack of leg seams will prevent chafing.

As mentioned, these do run small, which is problematic with a size range of XS-XL. The color palette is very muted and neutral.

Best for Sensitive Skin: Boody Full Brief

Pros

  • Great cut and design.
  • Comfortable material.
  • Sustainable sourcing and manufacturing practices.

What We Don't Like

  • The waistband needs a redesign.

Dermatitis, eczema, Tuesday - there could be a million reasons why nylon or spandex would not work for you. Luckily, there's now bamboo viscose that can solve those problems. It's stretchy, feels like silk against the skin, and it's eco-friendly. The only problem, at least when it comes to this full brief from Boody, is that the waistband tends to roll down.

Besides bamboo viscose, these panties also contain some nylon and spandex. The color palette is neutral with 4 shades of nude. However, the sizes range only from S to XL.

Best High-Waist Hipster: Everlane Invisible High-Rise Hipster

Pros

  • Completely lay flat on the skin.
  • Stays put even during intense workouts.
  • Super comfortable material.

Con

  • Glued seam.

This would have been a strong contender for our all-rounder if the seams were not glued. Textile glue is stretchy and can hold the bond for a very long time, but it can't compare to the good old thread. Other than that, these hipsters from Everlane are great for everyday wear and physical activities.

They are made from recycled nylon. And if you like green products, you will also like their eco-friendly packaging. The color palette leans mostly neutral, with nudes for both light-skinned and dark-skinned girls. The sizes range from XXS to XXL.

Best Low-Rise Boyshort: Tommy John Second Skin Boyshort

Pros

  • Non-pilling and anti-odor.
  • Comfortable and easy to move in.
  • High-quality materials and construction.

Con

  • Not suitable for all body types.

The Tommy John Secon Skin Boy Short sits very low on the hips and won't make even a slight peek when you bend over. On top of that, they are completely seamless and won't show under some of the thinnest and clingiest fabrics. However, they tend to be somewhat on the flat side, so you may not like them if you have some junk in your trunk.

They are made from 90% modal and 10% spandex and come in a rich palette of colors. Sizes range from XS to XXL.

Best G-String: Negative Underwear Glacé G-String

Pros

  • Silky feel from quality nylon.
  • The waistband doesn't dig into the skin.
  • Anti-pilling.

What We Don't Like

  • Expensive.

Seamless G-strings often leave us underwhelmed. Even when most of the body is well-made, the band still digs into the skin. Not with the Negative Underwear Glacé G-String. Even when stretched out to the natural waistline, it still lays flat without a crease in sight.

The G-string is made from a combination of lycra and nylon. The color palette is mostly neutral, and the sizes go only up to XXL. This is a little disappointing from a brand that is body-positive enough to have models with stretchmarks.

Best Active: Parade Thong Sport+

Pros

  • Well-made with strong interlock seams.
  • Approved by top-class athletes.
  • Quick drying.

Con

  • The middle section needs a redesign.

While almost any other pair from this list will not hinder your workout session, this is the pair to go for when you're looking for performance. The Parade Thong Sport+ is cooling, quick drying, and sweat-wicking. The leg opening design allows for a full range of movement, while the wide band ensures that they will stay put.

They are made from recycled nylon and elastane with a 100% cotton lining. They come in 6 colors, but no nude shades. The size range is decent and goes up to 3XL.

What to Look for in Seamless Underwear

Material

Shapewear is usually made from synthetic fibers like nylon or spandex, but modal may be better for seamless underwear. The former have a lot of stretch and a very long lifespan, while the latter offers the same benefits without the downsides.

Modal is man-made but from beech trees. It falls under the umbrella of fibers known as viscose or rayon. They were made from tree pulp to mimic long strands of silk fiber. However, they were also notorious for being fragile when wet.

That's not the issue with modal. It's durable, easy to take care of, and even 50% more absorbent than cotton. Plus, modal and other similar fibers are biodegradable and recyclable.

Another interesting and modern type of viscose you saw on this list is bamboo viscose. It's more durable than traditional viscose while being hypoallergenic. It's a better option for anyone with sensitive skin.

Cut

The perfect cut depends on your figure and the garment you plan on wearing.

If you have a tummy, you may need to go for a high0waisted model or for something that sits very low. Even with a high-quality pair, there's a chance of the waistband showing when it runs right across your belly.

The waistband is usually thicker than the leg openings, so that's the only part you have to pay attention to with most models. But if you're choosing a pair with compression or smoothing effect, go for as much coverage as possible. Skimpy models will make anyone look lumpy.

As for the garment, the classic brief will work under almost anything. However, when it comes to satin and bodycon dresses, it's important to pick a cut that matches the contours of your body as much as possible.

FAQ

What is seamless underwear?

Seamless underwear hides panty lines. Sometimes it also offers compression and smooths minor bumps and lumps.

Seamless underwear was originally designed for wear under costumes for dance, figure skating, gymnastics, etc. Now it's a go-to pick for wearing under leggings, jeans, bodycon dresses, and evening gowns.

They are always made from knit materials that allow them to have that raw and invisible edge. That same material offers a lot of stretch.

Usually, they are made from cotton, modal, nylon, elastane, spandex, or a mixture of these fibers. You'll often find most of them in different types of stretchy garments because of their elasticity, and that feature is a must when making truly seamless panties.

What's the difference between cotton and modal?

Both cotton and modal are plant-based fibers. However, there is a significant difference in how they are produced and behave once made into fabric.

Cotton comes from a plant that is similar to dandelions. Once it's ready for picking, it looks like little cotton wool balls. Then it's spun into threads that are either woven or knit to create fabric. Cotton fabrics are durable, heat resistant, and gentle on the skin.

Modal is made from beech tree pulp, just like rayon and viscose. Instead of being spun, the threads are extruded after processing. This allows modal to have that smooth texture that you would get from silk.

Modal is more heat-resistant and durable than viscose, has more stretch than cotton, and doesn't wrinkle, plus it's soft, breathable, and moisture-absorbent.
