Seventy percent of modern women wear a bra size that is too small for them and ten percent wear a size that is too large. This staggering statistic occurs because many women can’t seem to reconcile their real bra size with the bra size they have in their mind. Know that bra sizes between lingerie brands and bra styles can vary greatly. When picking out a new bra, be open to any and all sizes and be sure to focus on how the fit of the bra feels rather than the number of its band or cups.
