Where can I find clothes that can be tumble dried ?

Edinburgh Wool Mill is good for jumpers and cardigans that can be tumble dried too. My mum has a huge love of jumpers and cardigans, many of them wool, but these deteriorated very quickly (some turned into garments that would have fitted a doll...) so I no longer buy her anything wool.
I tend to wait for their sales as there are really good bargains, they are frequent, and they have a big selection of skirts and blouses too in nice styles and patterns.
