For the loose, oversized look on the picture I went up one size to XXL. It's perfect, fits over regular shirts fine, the arms are a bit tight over sweaters. Body is fleece lined, arms are cloth lined. The sweater is super cozy, the lining makes it functionally windproof, and so far this mild winter this with a thin sweater have been all I've needed. Even my husband thought it was cute and he almost never notices what coat I'm wearing. I call that a strong endorsement.

It was a Christmas gift, and my wife thinks it's great .

Amazing product, very warm.

Nothing but compliments on this purchase and its so warm too!

I got a XL a Large would have fit me but I wanted extra room for bulkier clothing I sometimes wear as it gets colder. It’s perfect and I love it! I will definitely buy another one soon.

Its very pretty and lookd great

Fits like a loose/oversized sweater which was exactly what I wanted. The sweater is pretty thick but feels very breathable. The construction quality also feels solid. The snap buttons on the inside were a nice surprise and they feel incredibly strong, no risk of them breaking or getting loose. Have yet to see how it'll fare in the laundry, but so far very happy with the purchase
