Getting washed and dressed: after work, better to avoid extremes (8)
I believe the answer is:
toilette
'getting washed and dressed' is the definition.
(process of cleaning and dressing oneself)
'after work better to avoid extremes' is the wordplay.
'after' means one lot of letters go next to another.
'work' becomes 'toil' (toiling is a kind of working).
'to avoid extremes' indicates the central letters (the extremes of the word are removed).
The middle letters of 'better' are 'ette'.
'toil' put next to 'ette' is 'TOILETTE'.
(Other definitions for toilette that I've seen before include "Washing, dressing, etc" , "Washing/dressing process" .)
