There's something about functional outfits that are also skin-tight. Swimsuits, no matter what form they take, are both functional and erotic in the right light. Swimming in the water just makes them all the more tighter, showing off just enough to entice us. Whole doujins are dedicated to school swimsuits, bikinis, and the like. So to honor one of the classic outfits, here are nine doujins that show them off in all their glory, whether or not the girl is actually using them in a pool.

Hopefully we'll be using swimsuits to hit the beach or pool soon. I think we're all done with winter. Bring on the summer!
