in this pic at the top of the tarp, maybe that is the hard shell part of suitcase laying open, the brown odd shape maybe is the leather that covered the suitcase that has come apart and curled up on one edge is why the shape is odd, the pink in top left of tarp looks like a bra. moo. subject to me deciding I see something different two min from now.
I agree, the pink item resembles a bra or a bikini with strings.
