1. Fit. A good strapless bra will not fall down! A good strapless bra is very fitted around the band, with the center gore lying flat against your breast bone and breasts not flowing over the top. This is a time to re-size if you haven’t in a while, which probably means going down a size in the band and up a size in the cup.
Silicone inside the cups of a strapless bra will give extra stay-up support. Skip the moisturizer and powder around the bra area for the silicone to work its magic!
