Wiggling leg in my revealing garment (8)
I believe the answer is:
negligee
'garment' is the definition.
(negligee is a kind of garment)
'wiggling leg in my' is the wordplay.
'wiggling' is an anagram indicator (letters wiggle around).
'my' becomes 'gee' (I've seen this before).
'leg'+'in'='legin'
'legin' anagrammed gives 'negli'.
'negli'+'gee'='NEGLIGEE'
'revealing' acts as a link.
(Other definitions for negligee that I've seen before include "informal attire" , "Nightdress" , "woman's underwear" , "Flimsy dressing-gown" , "Woman's flimsy nightgown" .)
