Glaring white robe over brown tee (7)
I believe the answer is:
blatant
'glaring' is the definition.
(I've seen this in another clue)
'white robe over brown tee' is the wordplay.
'white robe' becomes 'alb' (I've seen this in another clue).
'over' says the letters should be written in reverse.
'brown' becomes 'tan' (tan is a kind of brown).
'tee' becomes 't'.
'alb' backwards is 'bla'.
'bla'+'tan'+'t'='BLATANT'
(Other definitions for blatant that I've seen before include "Brazen, flagrant" , "Barefaced" , "Conspicuous" , "Totally obvious" , "Unashamedly open" .)
