Opaque bodystockings closely resemble the legged leotards that we often see gymnasts or dancers wearing. They are decidedly sexier, because they're usually made of a more delicate material like nylon. On the other hand, a sheer bodystocking is translucent. When you wear it, it allows more of your body to be seen. Whichever you choose, both are extremely enticing garments, perfect for arousing your mate.
