Dungarees
I believe the answer is:
jeans
'dungarees' is the definition.
('jean' can be a synonym of 'dungaree')
This is the entire clue.
(Other definitions for jeans that I've seen before include "Denim trousers" , "article of clothing" , "boys in France?" , "Are they worn by girls in Britian" , "(Usually) blue casual wear" .)
