Wedding collection of tense, naive painter (9)

I believe the answer is:
trousseau
'wedding collection' is the definition.
'trousseau' can be an answer for 'collection' (I've seen this before). I am not certain of the 'wedding' bit.
'tense naive painter' is the wordplay.
I cannot really see how this works, but
'tense' could be 't' (abbreviation used in many dictionaries) and 't' is present in the answer.
'painter' could be 'rousseau' (I've seen this before) and 'rousseau' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for trousseau that I've seen before include "USA routes (anag.)" , "Linen for a bride" , "Clothes collected for a purpose" , "not top-drawer stuff" , "Bride's accoutrements" .)
