Lynne,
I sympathise with you having been through this with my three girls. I think we did have to buy 'fashion -ish' ones sometimes but managed to find some in that polyester & viscose mix that feel more like heavy cotton, are warmer and more comfortable than the thin polyester ones,and mostly they came from New Look and Tammy Girl, although I recall sometimes buying from eg. Dorothy Perkins, Top Shop, or better still department stores eg. Debenhams (petite range perhaps?or try the 'Casual Club' section -I get my own cotton trousers that look more like trousers than jeans there and there are different leg lengths - short in my case! Plus they are a classic style (suit any age)and have pockets.)Hope this helps. regards
Annie
