Not sure where to find some that are good quality. CAn anyone recommend some online shops?

River island id try ,what size is she as holister does xs that would be a size 6 i think.there isnt may places to go, new look.if she fits into xs then u will have a better range to choose from x

Superdry sizes are small and the quality is good.
