We get it - it can be hard enough to figure out your correct bra size without throwing international differences into the mix. When you find out that a 36DDD/F bra in US sizing is a 36E in the UK, but an 80E in Europe, it’s easy to get confused! 😳

Here at Lavinia, we aim to make it as easy as possible for you to shop for lingerie which is why we convert all of our intimates to US sizing when we place them on the website. This way you can feel confident ordering your usual size, regardless of whether the bra was made in the US, the UK or Europe.

We know, however, that it can be confusing when you receive your new order only to find that the size differs on the label, so here’s a short guide on what you need to know about American vs European bra sizes.


European bra sizing vs the US sizing explained 

You may already know this, but what's unique about our lingerie shop is that we travel thousands of miles to bring you some of the finest European lingerie there is! We handpick beautiful intimates from dozens of suppliers and stock new collections shortly after we meet brands personally after the fashion and trade shows.

Choosing different bras and sizes

Now, let's discuss international bra sizing! First, the good news: Your band size number will be the same in both the UK and the US. When it comes to European sizes, though, it’s a different story. For example, the UK/US band sizes go from 28 to 52 whereas in most European countries it's 60-120. In France, however, they like to do things differently, so the corresponding band sizes are 75-105 instead.

As for cup sizing, everything is in sync up to the letter D — and after that, confusion reigns. A DDD/F in the US corresponds to an E cup in the UK and Europe, which then throws everything else out of alignment. To add to the confusion, the UK doubles up, with FF, GG, and HH, while the US and Europe progress in single letters up the alphabet. The letter I, meanwhile, is used as a cup size in the US, but not in the UK or Europe.

It's easy to see how all this American vs European bra sizing could send your head into a spin. Don’t panic, though, because we’ve done all the hard work for you and converted everything to the US sizing on every product page!

Discover more options with sister sizing

sister sizing guide by LaviniaHave you heard of sister sizing? It’s a clever way to work out which size to try if your bra doesn’t quite fit — if you’re trying out a new brand, for example — and you need to move up or downsize while keeping the same cup volume.

So, how does it work? The key is to remember that the cup size (the letter) is always related to the band size (the number) and that they work together. So let’s say you are wearing a 32C and it feels a little tight in the band. If you were to simply size up to a 34C, the band might fit but the cups would be too big.

To find the cup size equivalent, you need to size down in the cup every time you size up in the band, and vice versa. So the sister sizes for a 32C are 34B and 30D.

Got it? To find your sister sizes, look for your bra size in the chart above. Your sister sizes will be the ones immediately before and after it, working horizontally. For more sizing help with bras as well as panties, and other lingerie, visit our fitting room page.


The differences in sizing among bra types and brands

Before we let you go, we wanted to make a note that if you want to achieve the perfect fit, you should consider two other things in addition to your bra size and these are the brand you choose and the type of the bra. Why are these important, you may ask? 💭

Well, just like shops on the main street, every brand will do their sizing a little differently, that's why we recommend double-checking the measurements every time you buy a collection from a new brand. More importantly, perhaps, is to consider the style of the bra you're purchasing, especially if the type of fit is wildly different. For example, you may need to size up or down when shopping for a lace bralette compared to a deep plunge bra. 😉

    This article does NOTHING to help women that wear sizes that aren’t “average”. I wear a 36I/38H and STILL have no clue how to find the comparable European or UK sizes.We

    Sadly, too many women wear the wrong size bra. They don’t know how to measure to find their accurate size. But if they do, then they can’t find a store that actually carries the correct size because it’s not “common” enough. I use to force myself into a 38DDD because that was the biggest size I could find that sorta fit & since there was no other option I just went with it.

    I beg you…..for those of us who aren’t “average” PLEASE update this information for ALL of us!!!!!
