Gucci to review turning clothes blue (6)
I believe the answer is:
erotic
'blue' is the definition.
(I've seen this before)
'gucci to review turning clothes' is the wordplay.
'clothes' indicates the answer is hidden within the clue (the letters clothe the hidden word).
'turning' is a reversal indicator.
'citore' can be found hidden inside 'gucci to review'.
'citore' back-to-front is 'EROTIC'.
(Other definitions for erotic that I've seen before include "Conducive to arousing sexual desire" , "Calculated to arouse sexual thoughts" , "Dirty - blue" , "Amatory" , "Calculated to arouse sexual feelings" .)
