Hi I am trying to buy a dress for a little girl for Xmas , I need one with loads of extra space for her age I dont want her to be disappointed on Xmas day as all her siblings are easy to fit , I cant find anything looks dressy just very plain T shirt type dresses , I am hoping someone on here could recommend a brand to try I dont have exact measurements she is 7 but wears a 11/12 years which usually turns out very long , Thanks for an y help in advance
