Lands End! I love their "Beach Living" styles -you can get skirts and shorts to mix and match with different tops. Their stuff is high quality and lasts really well too. I highly recommend the Supplex material -it doesn't "hug" you or snag and it dries really fast. You will probably do better and find something more flattering in a tankini style than a one piece -although they do offer some skirted one pieces at Land's End.
