Difference Between US & UK Bra Sizing: Convert Chart For You

Welcome ladies!

Today’s topic is probably something that every woman finds too hard to process, understand or explain. Even though I’ve been in the lingerie industry for over a decade, it gets me every single time I mention it. So, ladies, this time, I’m going to explain every detail of the difference between UK & US bra sizing.

No worries. I’ll separate it into simple terms to comprehend.

On the off chance that your cup size is more modest than a DD, you don't need to stress over a thing. But if your cup size is bigger than a DD+, then follow me right away!

Same Band Sizes

Since manufacturers have different bra sizing standards, choosing which size for each of your bras is a daunting task indeed. But the key info I’m giving to you is that band sizes stay the same in US and UK sizing. For example, a US 32 band is equivalent to a UK 32 band.

Different Band Fabrics

Bra bands from different brands don’t follow a fixed quality of how tight or loose a band can be. For example, Wacoal, one of my favorite brands, has firmer materials and a tighter cut, whereas Natori (which is also on my top-fav list) uses more extravagant, delicate, and stretchy fabrics for their bras.

So, it’s pretty normal (and confusing at the same time) that you can find a 32-band size that is way loose or tight, depending on the brand.

Different Labels Of Cup Size

Here we go, the most complicated part. Unlike the UK size chart, American manufacturers don’t create any size alphabet that is beyond DDDD. However, some US brands label DD as “E” and DDD as “F”.

Look at this chart; is it a lot easier to visualize and understand?

Some Tricks You Don’t Wanna Miss Out

To make the game even harder for girls,  there are some US brands which are using the UK sizing systems. Yes, you’re hearing me. They may be cross-using a size chart from one another.

My first trick for ya is to look for what size-measuring method and which materials a manufacturer uses before ordering online.

My number two trick is that don’t forget to look at the UK and US equivalent sizes on the tags. Also, turn to the detailed and original bra size converter on the manufacturer’s website.
