Offer suit to sell back, keeping current winter clothing (8)

'winter clothing' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'offer suit to sell back keeping current' is the wordplay.
I cannot really see how this works, but
'current' could be 'i' (physics symbol) and 'i' is located in the answer.
an anagram of 'sell' is 'lles' which is present in the remaining letters.
The remaining letters 'woo' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
