I spent years looking for thin swimsuit material that dries up quickly. And I found it. In addition this top looks great. I need support and there are removable support cups that are so thin and they look natural. The top makes you feel very free (unlike some confined tops that are suit of armor type) but covers well, and provides support. And both neck and chest ends tie, so order based on the breast size, not the perimeter as that can be adjusted.
