polo necks

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

'close-fitting sweaters' is the definition.
'polo-necks' can be an answer for 'sweaters' (polo-neck is a kind of sweater). I am not sure about the 'close-fitting' bit.

'left individual covered in marks on skin' is the wordplay.
'left' becomes 'l' (common abbreviation).
'individual' becomes 'one' (an individual is one person).
'covered in' is an insertion indicator.
'marks on skin' becomes 'pocks' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'l'+'one'='lone'
'lone' going inside 'pocks' is 'POLO NECKS'.
