Intimate attire (8)
I believe the answer is:
lingerie
'intimate attire' is the definition.
'lingerie' can be an answer for 'attire' (type of clothing). I also know that 'intimate' relates to this answer.
This is the entire clue.
(Other definitions for lingerie that I've seen before include "Fancy underwear for women" , "stockings, say?" , "Ladies' underwear" , "Women's underwear and nightwear" , "Slinky undergarments" .)
