Taking sun top off fades what's usually beneath (6)
I believe the answer is:
undies
'taking sun top' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'off fades what's usually beneath' is the wordplay.
I cannot quite see how this works, but
'fades' could be 'dies' (I've seen this in another clue) and 'dies' is located in the answer.
The remaining letters 'un' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for undies that I've seen before include "Knickers (abbrev.)" , "Undergarments (colloq.)" , "Pants" , "Used in (anag) -- unmentionables" , "Lingerie -- is nude (anag)" .)
