100% cotton, gentle on the skin, off-white top and bottom set. I've only worn it once, so it's been washed. The socks and apron have not been used. It's easy to wash; I hand-washed it, but you can also put it in a laundry net and use a delicate cycle. Since it's getting warmer, you can wear it as a cardigan, or separately as a top and bottom. It's versatile, and I hope you'll enjoy its cuteness, which is only available now. I'd like to sell it to someone who understands.
