Woollen garment: button it, along with wig (5)
I believe the answer is:
shrug
'woollen garment' is the definition.
The answer and definition can be both related to bodily activities as well as being verbs in their base form.
Perhaps there's a link between them I don't understand?
'button it along with wig' is the wordplay.
'button it' becomes 'sh'.
'along with' means one lot of letters go next to another.
'wig' becomes 'rug' (rug is a slang term for a wig).
'sh'+'rug'='SHRUG'
Can you help me to learn more?
(Other definitions for shrug that I've seen before include "Uncaring gesture" , "Expressive movement of shoulders" , "indifferent response" , "Expression of indifference" , "Affect indifference" .)
