I'm a little stuck... Click here to teach me more about this clue!

'desperately one who's trying to look sexy?' is the definition.
I can't judge whether this defines the answer.

'about time pull in abdomen' is the wordplay.
'about' is an anagram indicator.
'time' becomes 't' (abbreviation).
't'+'pull'+'in'+'abdomen'='tpullinabdomen'
'tpullinabdomen' with letters rearranged gives 'PLATINUM-BLONDE'.

Can you help me to learn more?
