I've cut the tag off, but according to my purchase history, I think it's 12M. However, since it's Jacadi, it runs quite small. I think it would fit well for around 3 to 7 months. My daughter is quite big, so she only wore it about twice. I washed it in a home washing machine. For this season, I think it would be very cute to wear it with a collar peeking out from a knit sweater. Please consider it.
