Adorable and quality!
Size: Small, Color: Blue Cat
Adorable and excellent quality. Daughter didn’t like it at all though and it does run on the bigger side, but I’d still recommend. It’s warm, thicker not cheap material and color is vibrant and pretty!

Love this!
Size: XX-Large, Color: Blue Cat
I am a petit adult woman (usually xxs -xs, very fit). I got myself a L and was very pleased with a looser fit. It’s very cute and well made. I wish they had more designs that work for adults and I would totally buy more!! :D
