This was my favorite dress this spring, and the material was durable but comfortable for a x in valley heat. Office appropriate at tea length, accomodates a 38D with just a hint of tightness at the armpit. It wasn't enough to pinch, but might be uncomfortable if you have chubbier arm areas. I did wash and ruin in at a laundromat, as opposed to my machine that had washed it several times at times, so of your machine is finicky, handwash to save it! Will order a replacement soon
