Fitted leotard I fancy (8)
I believe the answer is:
tailored
'fitted' is the definition.
(thesaurus)
'leotard i fancy' is the wordplay.
'fancy' is an anagram indicator.
'leotard'+'i'='leotardi'
'leotardi' anagrammed gives 'TAILORED'.
(Other definitions for tailored that I've seen before include "Made to measure for idolater" , "(Of clothes) fitted, well cut" , "Fitted to requirements" , "Adjusted" , "Cut to fit" .)
