Cheap and showy (6)
I believe the answer is:
tawdry
'cheap and showy' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for tawdry that I've seen before include "Showy and gaudy but without real value" , "Tastelessly showy" , "Cheap and shoddy" , "Cheap and flashy" , "In poor taste" .)
