This is a Combi Comme Ca Ism duck romper. The size is 70. This is made of gauze fabric, which absorbs sweat well. It was a gift, but my baby outgrew it after wearing it twice. The baby didn't eat while wearing it, and wore a bib, so there are no stains or dirt (based on my personal inspection), and I think it can still be worn in good condition. How about it for summer wear for a baby born in winter? It will be folded compactly and shipped in simple packaging.
