I call bet off to be graceful (8)
I believe the answer is:
balletic
'be graceful' is the definition.
(I've seen this before)
'i call bet off' is the wordplay.
'off' is an anagram indicator.
'i'+'call'+'bet'='icallbet'
'icallbet' anagrammed gives 'BALLETIC'.
'to' is the link.
(Other definitions for balletic that I've seen before include "Like Swan Lake" , "Artfully flexible" , "graceful" .)
