Meeting patient finally, doctor wears this garment (10)
I believe the answer is:
sweatshirt
'garment' is the definition.
(sweatshirt is a kind of garment)
'meeting patient finally doctor wears this' is the wordplay.
'meeting' means one lot of letters go next to another.
'finally' indicates one should take the final letters.
'doctor' indicates anagramming the letters.
The final letter of 'patient' is 't'.
'wears'+'this'='wearsthis'
'wearsthis' is an anagram of 'sweatshir'.
't' put after 'sweatshir' is 'SWEATSHIRT'.
(Other definitions for sweatshirt that I've seen before include "casual gear" , "Long-sleeved top worn by athletes" , "leisurewear" , "Long-sleeved, knitted cotton sweater" .)
