Just having nothing to wear? (6)
I believe the answer is:
barely
'just' is the definition.
(barely can mean only just)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for barely that I've seen before include "how streakers like to act?" , "just a short while before" , "how babies are born?" , "Hardly" , "as Godiva rode?" .)
