Thick warm sweater

I like this rental. Options to wear with jeans or high waisted skirt. A bit cropped but not bad. Wasn't itchy and kept me warm.

Very cute top, nothing crazy. I wish it were a bit longer, it’s cropped, but that’s personal preference.

Nice sweater with a bit of interest to it

I like this sweater.The material was nice and not itchy. It was something that I could wear out with friends running errands and just added a little more show to a basic sweater.
