This Is How a Bra Should Fit
How Should a Bra Fit?
For a truly perfect fit, all four parts of the bra need to do their respective jobs in unison. The band, which is actually responsible for most of the support, holding your bra in place. The straps, which serve to keep the cups next to your body instead of pulling away. The cups, which should fully hold your breast tissue, without any gaping or spilling over. And, the underwire, if you choose this style, which should rest on your body, behind, rather than on, the breast tissue.
