DJ's cleaner? (7,5)
I believe the answer is:
evening dress
This could be a double definition.
'dj's' is the first definition.
(I've seen this before)
'cleaner?' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for evening dress that I've seen before include "Formal dinner wear" , "Formal attire" , "DJ" .)
