Porter checked French friend's jacket (8)
I believe the answer is:
camisole
'jacket' is the definition.
(I've seen this before)
'porter checked french friend's' is the wordplay.
I cannot quite see how this works, but
'friend's' could be 'amis' ('friend' in French) and 'amis' is found in the answer.
'porter' could be 'cole' (musician Cole Porter) and 'cole' is present in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for camisole that I've seen before include "Loose undergarment" , "Female undergarment" , "item of underwear" , "Short undergarment for women" , "Slip" .)
