Why does my bra ride up in the back?

Your bra rides up in the back because the band lacks the proper tension needed to anchor securely on your ribcage, which is the most common fit issue women experience with their bras. When your band is too loose or has stretched out over time, gravity pulls the cups downward in front while the back creeps upward, disrupting the level line that delivers optimal support and comfort. The band provides the majority of your bra's support, not the straps, so insufficient band tension forces your straps to overwork, often leading to shoulder strain and an uncomfortable lifting sensation.

Cup fit also plays a role in band stability, as cups that are too small or shallow push the bra away from your body, while cups that are too large remove the "anchor" effect, both scenarios contributing to ride-up. Smart construction features like wide wings, stabilized cradles, and supportive bands engineered to resist movement help maintain that level back line, while proper care preserves the elastic integrity that keeps your band snug and supportive where it belongs.
