Occasionally admits husband's a looker (4)
I believe the answer is:
dish
'a looker' is the definition.
(I've seen this in another clue)
'occasionally admits husband's' is the wordplay.
'occasionally' indicates alternate letters (letters taken at regular intervals or occasions).
'husband' becomes 'h' (abbreviation).
The alternating letters of 'admits' are 'dis'.
'dis'+'h'='DISH'
(Other definitions for dish that I've seen before include "Ruin" , "Container for serving food" , "Shallow bowl" , "Food container; aerial" , "bit of pottery?" .)
