I've been looking for a barely supportive (it does about 1/3 of the work of a real bra, which is what I was looking for) and sheer bralette for awhile now, which is hard when you have dds.  The xlarge fits me (I'm a 34 dd) perfectly  The perfect thing to lounge around the house in, or go out if you don't mind the mostly bra-less look.  As mentioned by other reviewers, it is see-through.  So, only wear it around people who you want looking at your nipples, or under a shirt.
