I believe the answer is:

attire

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

'dress' is the definition.
(I know that attire is a more specific form of dress)

'a teetotaller keen displeasure?' is the wordplay.
'teetotaller' becomes 'tt' (abbreviation).
'keen displeasure?' becomes 'ire' (displeasure is a kind of ire. I am not sure about the 'keen' bit.).
'a'+'tt'+'ire'='ATTIRE'

'causing' acts as a link.

Can you help me to learn more?

(Other definitions for attire that I've seen before include "12" , "Prepare" , "Formal dress or costume" , "Clothing - tear it (anag)" , "Habit" .)

I've seen this clue in the Evening Standard.
