Bill wearing woman's skirt (5)
I believe the answer is:
evade
'skirt' is the definition.
(I know that skirt can be written as evade)
'bill wearing woman's' is the wordplay.
'bill' becomes 'ad' (advertisement stuck on wall).
'wearing' is an insertion indicator.
'woman' becomes 'eve' (Eve is an example).
'ad' inserted inside 'eve' is 'EVADE'.
(Other definitions for evade that I've seen before include "Illegally escape (taxes)" , "Dodge by cleverness (5)" , "Escape, avoid" , "Shirk" , "Circumvent, dodge" .)
