Never worn. Tags say L, but fits more like an M. Selling because it did not fit. Whoever manufactured these for icebreaker, made them on the small side! :( Measures 13.5" across at the underbust, but stretches to 17". (It will fit you perfectly if you're a 30"-32" bra with a B-cup or less..34" is pushing it). Customers with larger cup sizes did not give this bra good reviews. Too bad these were discontinued. They were my holy grail bra! I live in mine.
