So You're A 34E...What Does That Mean?

So you’re a size 34E(DD)...what does that even mean?

So you measured yourself using our Size Calculator, maybe tried on a few bras, read all about how your bra is supposed to fit correctly - and you have determined you wear a size 34E(DD). Great! But what does that actually mean? Trusst is based on science and technology, and we’re always fascinated with problem-solving and learning new things. We thought it would be fun to put together some interesting data and facts around this 34E(DD) number so that you can really get to know your size - because it’s not just a’s a lifestyle.

Cup Volume

As a 34E(DD), your breasts weigh about 2.9 pounds. That’s a lot of weight to carry around! Good thing you have Trusst’s bra support technology to do the heavy lifting and take the pressure off your back and shoulders. We put together a few comparisons to this number to show exactly how much weight you’re carrying around every day:

Band Size + Cup Fit

Trusst bands fit true to your underbust measurement, which means that in a 34E(DD) you measure within a range of 32.5-34.5 inches. As you have probably learned by now, your band should fit snugly (but not too tight!) and should lay parallel to the floor.

Your cup volume fits when your breasts lay nicely inside of the cups, and there is no spillage or gaping. If you feel like you might be spilling, aka have the dreaded “quadboob” - we recommend sizing up a cup but keeping the band the same 34 size. This would put you in a 34F(DDD).

Our Favorite 34E(DD) Bra

Our favorite 34E(DD) bra is the Marjory because it has the support you need in a comfortable, stylish t-shirt design. Fully adjustable straps and a wide, 4-row hook back provide a smooth feel that lays nicely under clothes.
