Bests & Worsts Reviews from Amazon

Looked cute with great reviews (????), so I ordered. I received something much different from the picture. First, I got a medium and it looks like an extra small. I have very thin arms and it is tight on me; the "cardigan" is short, boxy and not cut with the nice long angled front shown in the picture. The fabric is extremely cheap looking. It is very thin, has black marks on the back and a pungent, offensive odor. There is nothing good I can say about the garment. I immediately contacted the seller. Their response- mail it to China (at my expense) and they would give me a refund! I told them the product was not as pictured, unacceptable and I expected a full refund. The seller stopped responding. See my pics please!
