teen girls clothing

Does anyone have ideas of stores and/or catalogs to buy stylish young teen style clothing for a girl with a thick waist? We went shopping yesterday and nothing she liked fit. My daughter essentially has no waist although she is not heavy. She has always worn elastic waist pants and shorts, leggings, or men's jeans and has not cared, but now she wants girl's bell bottoms with embroidered flowers on the legs and clothes that fit at the waist. We tried some women's clothes since she is tall, but the proportions were wrong for a young girl. I don't want her to be unhappy about her natural body shape, but fashion is working against me.
