This is a beautiful sweater. Im 58 and 115 lbs. and usually wear a size 0-2 (25 waist; 34 bust), and I got a S/M. I put my hand down, so you're able to get a general idea of the length, but keep in mind Im tall. The instructions say to hand wash and lay flat to dry. It seems like machine washing this item would ruin the quality. Also, it is a beige-pink. I would almost call it nude. Its really pretty on a darker skin tone, but I imagine itd be beautiful on a lighter woman, too. Its the perfect amount of over-sized; its enough to do the off-the-shoulder look I love.
