H&M Bodysuit Set of 3 Size: EUR 86, US 18M, CA 12-18M Likely equivalent to size 80-90. 100% Cotton Please check the button placement in the photos. These were worn until my child outgrew them, so there is some wear and tear. There is some fading. I have checked for stains and fraying, but there may be oversights. There may also be some shrinkage from washing, so please assume they are slightly smaller than the size indicated.
