Chief finished with fashion accessories, madly in love (4,4,5)
I believe the answer is:
head over heels
'madly in love' is the definition.
(I've seen this before)
'chief finished with fashion accessories' is the wordplay.
I cannot quite understand how this works, but
'chief' could be 'head' (synonyms) and 'head' is located in the answer.
'finished' could be 'over' (similar in meaning) and 'over' is found within the answer.
The remaining letters 'heels' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for head over heels that I've seen before include "normally upright?" , "In disorderly haste" , "(In relation to love) madly" , "topsy-turvy" , "Tumbling posture" .)
