Flowery knickers? (8)
I believe the answer is:
bloomers
'knickers?' is the definition.
('bloomers' can be a synonym of 'knickers')
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bloomers that I've seen before include "Mistakes, underpants, loaves or flowers" , "Loose-fitting knickers" , "clothes" , "Old underwear" , "made by clothing manufacturers" .)
