I have a size 110 cut-and-sew top, but it's slim, so I think a child who wears size 100 could wear it with the sleeves folded up a bit. It's been worn by a child, so as you can see in the photos, there are some stains. Perfect for playing in the park or at daycare. Long-sleeved cut-and-sew top featuring prints of trains and airplanes. - Brand: Grateful Scope - Size: 100cm - Color: Yellow - Design: Train and airplane print - Color: Mint - Design: Car and road print Thank you for looking.
