I used to think cups were just tiny hats for my chest. News flash: they are not. Your breast should fill the cup smoothly, like peanut butter spreading on toast. No gaps, no spillage.
If the fabric wrinkles or gaps at the top, you’re probably in a cup that’s too big. But if you’ve got overflow—that little bulge spilling out near your armpit or over the top—that cup is too small. It’s like trying to fit a chunky sweater into a tiny Ziploc bag.
Here’s a fun test: bend forward slightly and jiggle. If your breast stays inside the cup without a struggle, you’ve found a winner. If it makes a break for freedom, time for a different size.
