First person in Paris suggests the solution is to make trousers (5)
I believe the answer is:
jeans
'trousers' is the definition.
(denim trousers)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for jeans that I've seen before include "Casual trousers, sometimes stonewashed?" , "boys in France?" , "(Usually) blue casual wear" , "article of clothing" , "Strides casually" .)
