Petit Bateau - 3 pieces Size: 6m/67cm babyGAP - 1 piece Size: 6-12 months Uniqlo - 1 piece Miffy pattern Size: 70 This is a set of 6 undershirts. I used them from about 3 to 10 months old. The 3 Petit Bateau pieces have been worn a lot, so they show some wear. The Uniqlo and GAP pieces have been used a few times. I don't think there are any stains on any of them, but I apologize if I missed anything. I think you'll need a lot of undershirts, so how about these?
