ddd bra size

Just when you think you’ve figured out your bra size, it changes. If you’re struggling with finding a supportive DDD bra, we’re here to make it easier for you.

In this guide, we’re sharing the bra sizes that come after DDD and answering some of your most common DDD questions. Without much further ado, let’s get right to it!

Is a DDD cup size the same as an E cup size?

Yes, a US DDD is the same cup size as a UK E.

Why do some US lingerie brands use the size DD/E on their bra tags?

We think this is confusing too. Some US lingerie brands list a DD cup size as DD/E on their size tags. So if you see a DD/E on a bra that uses US bra sizing, keep in mind that the bra is a US DD. If you’re looking for an E cup, you’ll want to size up to a US DDD.

Should I buy US or UK bras?

This is entirely up to you! MOD By Parfait uses UK sizing, so if you usually wear a DDD in US lingerie brands, you’ll want to opt for an E cup size in our lingerie.

Why does bra sizing change after DD?

When it comes to US and UK bra sizing, the bra cup size (the letter) is the same for both US and UK sizing up to a DD cup. After a DD cup, US and UK bra sizing starts to look a little different. If you wear larger than a DD cup, you’ll need to convert your bra size from US to UK bra sizing or vice versa to get the right size. Remember: a US G cup will not fit the same as a UK G cup – though they have the same letter, a US G will fit smaller than a UK G cup.

Bra size tags for US and UK lingerie brands might look different, but it isn’t to confuse you. To convert your bra size to the right size, we’ve created a helpful chart here to make it easy and save you time. Once you’ve figured out your size in a brand, you can usually keep buying that size until your bra size changes or the lingerie brand discontinues that bra style.

Here are the bra sizes that come after US DDD or (UK E):

DDDD/G (US) or F (UK)

DDDDD/H (US) or FF (UK)

I (US) or G (US)

J (US) or GG (UK)

K (US) or H (UK)

L (US) or HH (UK)

M (US) or J (UK)

N (US) or JJ (UK)

O (US) or K (UK)

What is the bra sister size for DDD or E?

Do you wear a 34DDD or 36DDD bra? For a 34DDD, the bra sister sizes are 36DD and 32DDDD/G (US) or 32F (UK).

Where to buy DDD bras

Your local lingerie boutique is the perfect place to shop for DDD bras. They stock a wide selection of 30DDD, 32DDD, 34DDD, 36DDD, 38DDD, 40DDD, and 42DDD bras, among many other sizes.
