Setter caught wearing two lingerie items and 100 trinkets (4-1-4)
I believe the answer is:
bric-a-brac
'trinkets' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bric-a-brac that I've seen before include "Treasured odds and ends" , "Odd items of furniture, ornaments etc" , "Knick-knacks" , "Miscellaneous small objects, especially curios" , "Motley collection" .)
