#3 Make Sure Your Bra Fits

No, really. It needs to do more than simply clasp, it needs to hug the breasts, hold them up, and clearly separate them from blending in with your midsection. The straps need to stay in place all day too, no more slipping.

Think of it as a basic comfort thing. When a bra fits, it makes your shirt, dress, tank top, whatever, look better. Things fit better, and in turn, you feel good in them.
