Great for layering or wearing on its own!
I’m 5’6” and ordered the small — it fits perfectly! The color is exactly as shown in the pictures, a beautiful beige that goes with everything. The fabric is incredibly soft and comfortable, making it great for layering or wearing on its own. I’m really happy with this purchase and would definitely recommend it!

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.
