Bought these for my daughter to replace the pants that came with the costume (for Mel, from Disney descendants). She just turned 7 and wears a small (6-7) in Old Navy leggings and I ordered a small 6 in these. They're a bit bigger (both in width and length) than her little old navy blue leggings, but they're quite nice, comfy, etc. and will look great with her suit and even end up fitting under a sweater dress or something the Season. .
