Odette Open Cup Bra Scarlet

Open cup bras, by their very nature, won't offer the same full support and coverage as a traditional bra. The focus is on lift and shape.
Band size is crucial for open cup bras. Make sure the band is snug and sits comfortably around your ribcage. It should provide the primary support.
Cup size might be slightly different than a traditional bra. Since it's an open cup, you might find that your usual cup size still works, or you might need to adjust slightly (perhaps a half size up or down) depending on how the cups fit on your breasts.
Consider the style: The Odette likely has a defined shape. If you have wide-set breasts or breasts with a different shape, the open cup's structure might affect how it fits.
