Puts on something saucy? (7)
I believe the answer is:
dresses
'puts on' is the definition.
(dressing is a kind of putting on)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for dresses that I've seen before include "sacks, possibly" , "falls into line" , "Gets tired" , "Decorates" , "Costumes" .)
