Be uncomfortably hot over getting quite stripped down in this? (7)
I believe the answer is:
wetsuit
'this?' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'be uncomfortably hot over getting quite stripped down' is the wordplay.
'be uncomfortably hot' becomes 'stew' (to stew is to remain uncomfortably hot).
'over' is a reversal indicator.
'getting' means one lot of letters go next to another.
'stripped down' says to take the centre.
The middle letters of 'quite' are 'uit'.
'stew' reversed gives 'wets'.
'wets'+'uit'='WETSUIT'
'in' acts as a link.
(Other definitions for wetsuit that I've seen before include "Garment worn by some skin-divers" , "Garment worn by a diver" , "diving gear" .)
