I received this, but the size and season didn't quite match, so I haven't been able to wear it much. Both the outer fabric and the lining are 100% cotton. It's a thick gauze material, making it very comfortable and soft against the skin. The blouse is easy to put on a baby with buttons. There are gathers on the sleeves and under the chest, giving it a gentle, fluffy look. The dusty pink fabric and small floral pattern are cute, and it's adorable when worn as a set! It's also cute worn separately. Because it's long-sleeved, it seems like it can be worn for a long time in the coming seasons.
