A small, cardboard one

Ami hefted the light, cardboard box . It's label said " Catch Me ! " and in smaller print "brand fishing gear". She was able to slide it over her torso. So long as she held it in place, it covered her from just below the buttocks, about an inch above her nipples. It was flimsy cover, but better than nothing. Trying to avoid jouncing it too much as she walked, Ami planned her next move. She stepped back, flustered when a puddle reflected her legs, showing quite a bit of bum from that unfortunate angle. Pulling the box down showed even more cleavage.
