I use Handful bras as both my sports bra and day-to-day bra (separate ones for each use (: ). I think I found out about them through a recommendation here a long, long time ago. They're comfortable, wireless, fit well (similar cup size as you and a big swimmer's back), and the straps are convertible for either criss-cross or straight. No one can tell that I'm wearing what's technically a sports bra under my work clothes, even with light colored shirts/sweaters. Woman-owned company and Made in the USA!
