Why do bras ride up?

Bras ride up primarily because of a loose or stretched-out band that cannot provide the anchoring support your body needs. When your underband lacks proper tension, it slides upward while forcing your straps to overwork, creating an uncomfortable see-saw effect where the back creeps up and the front slides down. Over-tightened straps, cups that are too small or shallow for your shape, and worn elastics compound this issue by shifting weight away from the band.

The solution lies in finding the right band size, properly adjusting your straps, and choosing cup shapes that match your body's needs.
