This is a jumpsuit from hakka baby. Size: Free The inside is made of fluffy fleece material, and the hands and feet can be turned over, so it's windproof. Reversible. The feet can be separated or connected with buttons. I think this one piece is enough to wear over clothes, such as when putting the baby in a stroller. I've dressed my baby in it several times, but it's in good condition. The size is suitable for babies up to about 80cm.
