Girl, coy and attractive (5)
I believe the answer is:
dishy
'attractive' is the definition.
('dishy' can be similar in meaning to 'attractive')
'girl coy' is the wordplay.
'girl' becomes 'di' (**).
'coy' becomes 'shy' (I've seen this before).
'di'+'shy'='DISHY'
'and' is the link.
(Other definitions for dishy that I've seen before include "Good-looking (informal)" , "Gorgeous" , "Fair" , "Attractive" , "Informally good-looking, like plate?" .)
