I bought these to use for a college dance recital, and it was a disaster.
The girls sizes ran from S to L, and I read in a different review that the pants ran small so I ordered all of them a size up from the girls' usual sizes. I got them in and they looked fine, but in trying them on, it doesn't fit at all.
For most of the girls, they couldn't get the pants on past their thighs let alone zip them up, and for those who managed to get them on and zippered, they were too tight to dance in and the girls couldn't move.
Along with that, the sequin bits were not sewed in enough to actually move around in, so the second the girls tried walking in them, the fabric the sequins were sewn to ripped and exposed skin.
Short version, don't bother buying these. I've never had this much of an issue before with DDS merchandise before so I'm hoping it's just a fluke product, but still find another bottom from the site to use instead. I was so disappointed that these didn't work out.
