Your bra size changes more often than your favorite playlist. Weight fluctuations, pregnancy, or even a new workout routine can shift it. That “34B” you’ve worn since college? It’s probably a ghost.
The band is the real hero here. It does 90% of the support work. If your band is too loose, your straps will scream for help. A proper fit means the band stays level, even when you jump.
Fun fact: The cup size isn’t a fixed volume. It’s a ratio between your ribcage and your bust. So a “D” cup on a 32 band is totally different from a “D” on a 38 band. Science! (And boobs.)
