Following on from some threads recently where people have been struggling to find clothes that fit their little girls, I can vouch for New Look.
They have a 915 range that has shorts and combats with elasticated waists (my 9 YO DD hates anything tight on her waist and doesn't have a defined waist shape contrary to the opinion of most clothes designers - she is straight up and down and jeans are a nightmare to fit, in fact she hasn't worn jeans since she was about 3).
We went to New Look at Bluewater yesterday and I got her quite a few bits and pieces for our holiday at reasonable prices. Some lovely swingy tops with thing straps in lovely fabrics, one is in purple and blues with a few sparkly sequins sewn in for a bit of sparkle.
Plus at the moment there is 20% girls stuff. go go go!
