Calling any of the fairer sex with experience-

Wife is short (5'2") but with size 14 hips. Can anyone recommend tights (looking for warm ones not just lycra) that can be bought at different lengths or that are short enough? Was thinking of dnb range but they are not length flexible and concerned they will be too long.

Any ideas?
