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

'somewhere to sell clothing from equipment' is the definition.
I know nothing about this answer so I can't tell whether this works.

'two stains?' is the wordplay.
'two stains?' means two substitutions for 'stain'.
'stain' becomes 'spot' (synonyms).
'stain' becomes 'market' (I can't justify this - if you can you should believe this answer much more).
'spot'+'market'='SPOT MARKET'

'bearing' is the link.

Can you help me to learn more?
