I bought this before my baby was born, so the size didn't fit, and I've never dressed my baby in it. I selected 70cm because it's for 2-4 months. I think it's made of fluffy fabric and will be warm! A set of pink, fleece-material, polka-dot hooded jacket and pants. - Brand: H&M - Size: 2-4M - Color: Pink - Style: Hooded jacket and pants set - Material: Fleece - Design: Polka dots - Sleeves: Roll-up sleeves Thank you for looking.
