Vanillachocolate asymmetrical blue cropped eyelash sweater, size M, NWOT

Sizing is so confusing. This interesting little asymmetrical cropped eyelash sweater was listed as a size XL when I bought it, but of course, sizes are utterly meaningless when you buy stuff online. This is clearly meant for someone willowy, angular & relatively flat chested, or it just looks silly. I'm guessing maybe a size M would work since that's around my model's size. I've tried it on, but it's really not for me - this has never been worn. Vanillachocolate is a Chinese brand (based on the sizing and creative writing on the label), so I definitely should have known better, but it really is stunning when worn by someone who is the right size and bidy type. Also, it's my favorite colour, although my model insisted on calling it "Grover blue." So if your style is Avant-garde Muppet Fashionista, this sweater is for you.
