Garment size
I think it could be either:
'garment size' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for large that I've seen before include "Big, outsize" , "Wide-ranging" , "Big, great" , "substantial" , "Big < burly" .)
'garment size' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for small that I've seen before include "Piddling" , "Of no great size" , "Unimportant; young" , "Not great (in number)" , "Minute" .)
