If You’re One Of These Two Bra Sizes, You’re Probably Wearing The Wrong One!


3. All of your bras are the exact same size.

Not all bras are created equal. Just because you’re a 34B in a demi bra doesn’t mean you’re a 34B in a full-coverage bra. “Think of it like jeans,” says Altman, “You might be a size 28 in boyfriend jeans, but you may need a bigger size in skinny jeans.” Like denim, different style bras have such specific fit and can vary by brand.

Demi bras are low-cut—sometimes called “half cups”—and they have significantly less material than a full-coverage bra in the same size. So you may wear a 34B in a demi bra but a 34A in a full-coverage, says Altman.


Still not sure?
When in doubt, head to a specialty store for a bra fitting. “A good fitter will bring you a few sizes and a few styles so that you can really find what’s right for you,” says Altman. Wear a light T-shirt so that the fitter can get as accurate a number as possible when taking measurements.

“Would you wear a size 8.5 sneaker when you know that you’re an 8?” asks Altman. “Absolutely not.” Your boobs deserve to be treated just as well as your feet (if not better).
