Something worn in crowd lifted, boy in hat (6,6)
I believe the answer is:
bomber jacket
'something worn' is the definition.
(type of jacket)
'crowd lifted boy in hat' is the wordplay.
I cannot quite see how this works, but
'crowd' could be 'm' and 'm' is present in the answer.
'boy' could be 'bob' (short for Robert) and 'bob' is found in the leftover letters.
This explanation may well be incorrect...
'in' is the link.
(Other definitions for bomber jacket that I've seen before include "Garment styled on those worn by WWII flying crews" , "Zip-up garment with elastic waist and cuffs" , "Zip-up garment elasticated at the waist and cuffs" , "Article put on" .)
