This is a Petit Bateau crew neck cardigan. Made of 100% cotton. It's thin, so you can wear it in the summer to avoid air conditioning. Also suitable for early autumn and spring. The polka dot print is cute. I bought it but my child outgrew it without wearing it. 5 years/110cm Color: Navy Pattern/Design: Polka dots Sleeve Length: Long sleeve Length: Mid-length Neckline: Crew neck Season: Spring, Summer, Autumn
