Stand sideways in a mirror. The underwire (if there is one) should sit right where your breast meets your ribcage, not on breast tissue. If it’s resting on your boob, the cup is too small. If it’s poking your armpit, the cup is too wide or the band is too high.
Also, check that your breast isn’t being pushed forward into a “uni-boob” or flattened. A good fit creates a smooth, natural shape—like a calm lake, not a crashing wave. Remember, you’re looking for harmony, not a miracle.
When In Doubt, Trust the Feeling
Finally, the most chill indicator? Forget it exists. You should be able to wear a bra for a full day without thinking about it. No constant adjusting, no digging, no red welts. If you’re messing with it every ten minutes, it’s not you—it’s the bra.
Bras are like jeans: sizes vary wildly between brands, so ignore the number on the tag. Focus on how it feels when you move, breathe, and laugh. And if you’re still not sure? Walk into a shop, ask for a fitting, and be weirdly curious about the process. Your body will thank you with a quiet, comfortable day.
