Suitable for a holiday (6)
I believe the answer is:
festal
'suitable for a holiday' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for festal that I've seen before include "Relating to a festival; joyous" , "Jovially celebratory" , "Jovial" , "Joyous, festive" , "Relating to a holiday" .)
