Two types of sleepers, with different designs and materials, to keep your baby warm. Thin, Polka Dot - Size: 33cm x 52 cm - Material: 80% cotton, 20% polyester Fluffy - Size: 35cm x 50 cm - Material: 100% polyester Thank you for viewing. Although there is no clear clothing size listed, I think it's around 80-90cm! I'm selling them as a set because I think you can use both: the thin one in the hot season to protect from the cold of the air conditioner, and the fluffy one in winter so you can rest assured even if your baby kicks off the futon.
