This is a set of a bib and pants. I think it's perfect for a baby shower gift. Pants length: 31cm Hip circumference: 63cm The elastic waistband fits waists from about 38cm to 50cm. Based on general baby clothing sizes, it's about size 70. However, It's a size that can be used from around 3-4 months when drooling increases, to over 1 year old. Even when they start walking, these are relaxed pants with plenty of room, so they won't hinder movement, and you can let your baby wear them with peace of mind. I made items from the same material for my son and had him wear them, and the fabric is quite sturdy, so it didn't wear out easily and lasted a long time. 100% cotton. This is a handmade product.
