Very cute

Very cute and soft, but does run a tad bit big but not too much if you like it a little oversized. Will be sizing down one.

Good item
Size: Small, Color: Lime Green
I really like this sweater! It’s comfortable and it’s perfect with jeans, pants or skirt for that matter. I like that it’s a little baggy. I air dry after washing, my personal preference.

Lovely soft cozy sweater
Size: Small, Color: Eggshell White, Size: Small, Color: Eggshell White
This sweater is extremely soft and cozy! It’s also stylish and has a good feel and quality to it. It looks more expensive than it is. You could wear this to a holiday party, work or just a cozy night in what more could you want in a sweater? ❤️
