I was delighted with the quality and color
Size: X-Small, Color: Lilac
This is a super cute, and frankly, fairly high fashion little hoodie. The price was great for what it is. Really nice soft (terry?) inside. Double fabric hood. Really soft. It has an oversized cut which makes it easy to get on and off, but is just the right length to make the sizing look great and intentional - it doesn't look too big. I love the color. It's high quality, and I didn't notice any shrinkage. Even the hood is cut in a chic way. Not your average kids' hoodie.
