Scan garment label again
I believe the answer is:
readdress
'label again' is the definition.
('address' is an answer for 'label' so perhaps 'readdress' is OK for 'label again')
'scan garment' is the wordplay.
'scan' becomes 'read' ('read' can be a synonym of 'scan').
'garment' becomes 'dress' ('dress' can be a synonym of 'garment').
'read'+'dress'='READDRESS'
(Other definitions for readdress that I've seen before include "Have another look at" , "forward" , "tackle again" , "change direction" .)
