So what do you do if you've there are signs your bra is too small? Get a bra fitting of course. As Ra'el Cohen, vice president of design and product development at ThirdLove, told Refinery29, "I think the biggest mistake that women make is saying, 'I'm a 34C, and I've always been a 34C." The fact is, you're likely not the same size you were when you started wearing bras!

Cohen goes on to explain, "Your body changes on average six times in your life, so chances are, unless you've recently been fitted, you're going to be a different size — and that's okay." Getting a regular fitting, even once or twice a year, will ensure you're always wearing the right size. After all, "[a] bra that fits you correctly, and is the right size and shape, will allow the body to function at its maximum potential," chiropractor Dr. Rubina Tahir, DC told Bustle.
