Great sweater
Color: Seaweed Green, Size: X-Large
Fantastic sweater. True to size. Color is vibrant. Basketweave texture makes it look like a much more expensive piece. I get compliments every time I wear it.

Looks amazing
Very nice material and feel. I got complimented on this in public and it made my day, and completely validated the purchase for me. A soft material that looks and feels right when worn. I will buy more.
