A big cravat from the many in store (5,5)

I believe the answer is:

large stock

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

'the many in store' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'a big cravat' is the wordplay.
'a big' becomes 'large' (I've seen this before).
'cravat' becomes 'stock' (stock is a kind of cravat).
'large'+'stock'='LARGE STOCK'

'from' is the link.

Can you help me to learn more?

I've seen this clue in the Evening Standard.
