This is a set of 5 Petit Bateau long-sleeved bodysuits. They stretch well and I loved that they didn't get noticeably fuzzy even after washing. There is some wear and tear, such as a stretched neckline and a light stain on the neckline of the blue heart one, but I think they can still be worn. They are labeled 12m/74cm, but my average-sized child was able to wear them around 3 months old, with just the sleeves folded up. My child is now 1 year and 3 months old and could probably still wear them, but I have too many, so I'm selling them. ☺︎♡
