The Micro Bikini from Bare Rose turns out to be one of those stunning OMG gotta have that items that ends up hardly ever getting worn. I cannot recommend this sexy two piece that comes in a variety of colors for a couple of reasons. First, it's very difficult to adjust the horrible prefit and, since the items are no copy, no backups can be made in case you make a mistake. Second, since the top is a prim attachment, significant body movement causes the top to uncover what it is covering for all those that have enhanced physics enabled. The bikini does, however, make a nice piece for static modeling as demonstrated in these composite RL/SL photos:
