I think the gap size is around 70. It says 6-12 months. The two from Nishimatsuya have summery patterns and are very cute ☻ The size is 60-70. Purchased in July of this year. All three have only been worn about twice. No individual sales. Please purchase only if you understand that these are used items. #ShortSleeveRompers #BoysRompers #Nishimatsuya #ShortSleeves #Rompers #gap #gapBaby
