Teased for being poorly clad (6)
I believe the answer is:
ragged
'teased' is the definition.
('rag' can be a synonym of 'tease')
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for ragged that I've seen before include "Played practical jokes - in tatters" , "Describes worn or torn clothes" , "Shabby" , "Teased; untidy; badly dressed" , "ridiculed" .)
