A simple top, but one to get excited about! By European Culture its a predominently bamboo fabric outer, with a full body lined in silky viscose & bamboo blend, with a little elastine for stretch too. The hemline is in the lining fabric with 3 channels and a pull toggle if you wish to wear it tighter at the waist. The medium measures 40" at the chest, so it's a loose fit. Wash at 30 delicate and dry naturally.
