Stock of jeans, in a manner of speaking (8)

I believe the answer is:

pedigree

I'm a little stuck... Click here to teach me more about this clue!

'stock' is the definition.
(pedigree is a kind of stock)

I can't explain the rest of the clue.

(Other definitions for pedigree that I've seen before include "Lineage of thoroughbred" , "List of ancestors" , "Stock" , "Ancestry of a purebred animal" , "High-class" .)

I've seen this clue in the Irish Times.
