Nice but not great
Fits true to size. I ordered a small and it was a great fit. Could be a bit softer. Loved the style. Not too thin or not heavy, nice weight. This quality of the sweater was nice, however the buttons broke apart as I was styling the cardigan. Not happy to have to sew on small buttons to fit the small holes. It’s nice but I had to put too much effort into wearing it.
