I'm looking for casual dresses. There is no shortage of them, some very nice, but I don't want them to be too short. I have slim legs, it's not really the legs that are the problem, but I don't want to be walking along having to tug my dress down every few steps. Dresses in all the main high street shops seem to be either long or really really short. Or am I just looking at them on super tall models and actually on 5 foot 4 me they would be ok?
