Material: Milk Cotton (feels like a soft flannel) & Knit Cotton (95% Cotton/5% Spandex blend)
Fit/Sizing Info: In the Infant and the Kid's sizes these are fitting at the top of the size range. For example, in the romper, the 3-6 months fits like a 6 month, the 18-24 month fits like a 24 month or 2T; in Kid's sizes the 4-5 fits like a 5, the 6-7 fits like a 7, etc. If an older child needs larger than an size 12, we recommend sizing up to an adult small. The Men's & Women's are cut the exact same (the Women's doesn't have a more feminine cut to it, so if a boy needs to size up, and then Men's Small would be too large, they could do a Women's Small. The tag would just say "Women's S", but the fit would not be a Women's Fit. A sizing chart is posted in the pictures.
