Hi there! We ordered the C2 brief for my daughter in pink stripe. It’s adorable, but too tight, so we’d love to share it! She wears a size 8 in girls cotton briefs from Target, but we get them quite big so she doesn’t feel uncomfortable, so I thought this would fit! I admit I didn’t measure super well either. Follow their measurement chart (on their Etsy shop) for best sizing, but I think a kiddo who wears a 6/8 in undies would like this! Love the quality and style. Message me here or email me at peatuttle@gmail.com if you’re interested 🙂
