Heavy shoe enclosing sheer garments (8)
I believe the answer is:
clothing
'garments' is the definition.
(I've seen this before)
'heavy shoe enclosing sheer' is the wordplay.
'heavy shoe' becomes 'clog' (I've seen this in another clue).
'enclosing' means one lot of letters goes inside another.
'sheer' becomes 'thin' (similar in meaning).
'clog' enclosing 'thin' is 'CLOTHING'.
(Other definitions for clothing that I've seen before include "Apparel, garb" , "wardrobe" , "See 8" , "Garments" , "trousers?" .)
