Costume that's seen straight after tango? (7)
I believe the answer is:
uniform
This might be a double definition.
'costume' is the first definition.
(both can mean clothing)
'seen straight after tango?' is the second definition.
I know that 'tango' relates to this answer. I also know that both the answer and definition are singular nouns
'that's' is the link.
Can you help me to learn more?
(Other definitions for uniform that I've seen before include "Codeword following Tango" , "Regular - formal dress" , "Regimentals" , "Military wear" , "Unchanging, showing no variation" .)
