This is technically a size M but it FITS LIKE A SMALL. I bought this from the real real finale sale and it’s too small. I am a size 8 and the M was too small - felt more like a small. Would fit a size 6 or below. Ordered the same jacket in a Large because it’s amazing quality and so cool. The jacket is well lined so is a perfect winter going out jacket to keep you warm! New leather jackets from this brand are more than $1,200!
