Openly outrageous (8)
I believe the answer is:
flagrant
'openly outrageous' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for flagrant that I've seen before include "Conspicuous, blatant" , "Shocking" , "'Conspicuous, glaring (8)'" , "Being shameless" , "Of unconcealed outrageousness" .)
