If your tights drawer is filled with pairs that you, um, liberated from shoots, then it's probably best to check to see if they are giraffe sized before you go dancing in them, otherwise you will spend your evening hoicking your tights up from around your ankles where they will be wrinkling in folds, just like Nora Batty's.
Or maybe better still, get your assistant to tell a couple of the tights PRs that the model is abnormally short, say 5'6", and will require size medium, rather than size extra tall...(Only for the more amoral fashion editors out there...)
