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' indicates putting letters inside.
'sheer' becomes 'thin' (similar in meaning).
'clog' going around 'thin' is 'CLOTHING'.
(Other definitions for clothing that I've seen before include "Apparel, garb" , "wardrobe" , "See 8" , "Garments" , "trousers?" .)
