I am 5"4 , 123 lbs and purchased a S cause it looked quite large on the model and I wanted more of a smug fit. The Black-Grey (pictured) is darker than pictured on model, it is almost black, but it is a great fit and cause the fabric is quite warm and crosses over for extra warmth. I think its a great option cause you won't find a sweater like this in the stores! I even purchases a second one in green. The Black-Grey came quickly but the green one took a while to come, but was worth it especially cause the price was great.
