These are great leggings! I got them for my 8 year old sister who normally wears size 7/8 in stores. I bought her the l/xl and its perfect.  Super soft and she says they're are comfy. I do wish they had the more yoga top like the adult ones of this brand, not that my sister noticed or cared, shes not picky. I don't know home long they will fit her though. I have the adult ones in the 0-12 size and theres a big size gap that I wish this brand had a size for. Like the tween size in lularoe leggings. My sister will surely outgrow these ones and not be able to fit into the other size for a while. Thats the only down size though.
