The sweater is prettier in person than online. great quality, tight knit, overall good purchase. however, it does run small. i would absolutely size up. i am a size 4 with a 34 c chest and i ordered a m and i would have been happy with a roomier l. i was going to return to my local store but they were sold out in the larger sizes.
i will keep it because it's gorgeous and i'll make do with the less relaxed fit, but it doesn't look on me like it does on the model.
