The positives - lightweight but very warm, material and design is nice and floaty, a good length. I often tied around my waist for two weeks on a warm holiday and no change in shape of sleeves and the material coped with a loose knot.
The negatives - sleeve are WAY too short. I end up pushing them up all the time because they feel strange ending on my forearm and not my wrist. I have a slightly wider cardigan than I'd probably need (size availability) so I can imagine sleeves would feel even shorter with less generous material at the shoulder.
All in all, a smart cardigan that I wear daily for warmth that can be tied around my waist or scrunched into my tote bag if I need to.
Goes without saying that it resists odours and I've only washed it once or twice since I got it in September.
