Gluttony uh... yea doesn't strike me as the type, no hints to being any type of glutton.
Lust Too cute for lust... and too clothed XD
Envy Just doesn't quite fit.
Pride
Greed Outfit is too simple to be expressed as being wanting.
Sloth This was a close second but she seems more energetic than that... by a little.
Wrath Doesn't look angry at all =P

I say Pride. Dressed sharp yet simple. Make-up and scarf draws attention, but remains tasteful. Holds an air of "I'm better than you".
