While it would be nice, bra fitting is not a one-time deal. You need to go back for regular bra fit check-ups. “Women get married to their bras. They tend to wear the same bra for five years, even when they are bad and ill-fitting,” explains Koch. Don’t let this happen to you. Edmark suggests getting fitted every six months, while Koch recommends once a year.

And those aren’t the only times you need a fitting. If you experience a big life change, like weight gain (or loss), the birth of a child, changes in diet, or a new exercise regimen, it’s time to get your booty — and boobies — to the bra experts.
