Guess sweater/sweater minidress size S

I love this but it ended up being too tight for me. There are a couple of small very light stains, you can probably get these out easily- I just haven’t tried. I have provided photos- one on the back, and slight but barely noticeable yellowing under armpits. No smells or other flaws, like new. A petite “small” I would say, although it’s stretchy material. Measurements laid flat (roughly): Shoulders: about 32cm Length: 72 cm Waist: 31 cm
