I bought this for outings and wore it for one season. It has buttons at the inseam, so you can change diapers easily. I think the size is about 70. Material: Cotton I've written my name on the quality label, so I will cut it off before sending it! ******************** I am selling my son's clothes as he grows. They quickly become too small, so I only wear them for one season. I hope you will reuse them. ★ No discounts. I will discount the shipping cost for those who purchase multiple items! ★ Please refrain from purchasing if you are concerned about stains or wear and tear. ★ I do not smoke, but I have a cat.
