Stone fireplace held clothing (7)
I believe the answer is:
singlet
'clothing' is the definition.
(singlet is a kind of clothing)
'stone fireplace held' is the wordplay.
'stone' becomes 'st' (abbreviation).
'fireplace' becomes 'ingle' (I've seen this in another clue).
'held' indicates putting letters inside.
'st' placed around 'ingle' is 'SINGLET'.
(Other definitions for singlet that I've seen before include "top gear" , "Sleeveless vest" , "Tingles in vest" , "garment worn by men" , "Sleeveless shirt" .)
