Ralph Lauren Beaded Top/Mini Skirt/Scarf Size S Black

I'm not exactly sure what to call this! Lol! I have worn it as a sleeveless top, a mini skirt with leggings underneath, and as a neck warmer scarf. It has tasteful glass beading and the knit design has holes in it. It is stretchy but not super stretchy. I wore it when I was a 4 to 6. It has no size, so I am estimating it as a size S. Relaxed it measures 12" wide and 18" long. It is black with black and iridescent beads Size SM (?) It is 40% Rayon/30% Cotton/20% Wool/10% Nylon. Dry clean.
