I saw someone else wearing this sweater and had to find it! i'm 5'5"and 118 lbs and ordered the small. the back of the sweater hits a few inches above my back pockets. i've been wearing it with a tank underneath and it's been the perfect sweater for fall weather. i was worried the poncho effect might make it hard to wear this sweater with a jacket but it's actually less bulky than other "real" sweaters i have.
