She's a match for anyone (5)

I believe the answer is:

vesta

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

'match for anyone' is the definition.
I can't tell whether this defines the answer.

'she's a' is the wordplay.
'she' becomes 'vest' (I can't justify this - if you can you should believe this answer much more).
'vest'+'a'='VESTA'

Can you help me to learn more?

(Other definitions for vesta that I've seen before include "Roman goddess; match" , "Hearth goddess; a match" , "heavenly body" , "Asteroid; goddess; match" , "Stave (anag.)" .)

I've seen this clue in The Globe and Mail.
