Girls - Would you wear swimsuits with optional leggings?

I don't think I would wear a swimsuit with leggings attached. If I saw other girls wearing legged swim suits I would think it was odd. It might be alright as long as the leggings and swimsuit matched. The girls in your picture don't look very good because their leggings and swimsuit clash. I couldn't see this as a fashionable thing, but rather as a useful thing if it was very cold where you were swimming.
