Mmm. a bit of a tricky one.... I'm thinking of Charlotte from the Sex and the City movie...gloves, pearls, beautiful (new) outfit maybe??
Or Kim from Kath and Kim, you could be a pregnant hornbag..noice!

Juno (though I haven't seen that one)

Oooh just thought of another one...That chick from Degrassi Junior High...Spike??

Can't think of any others at the moment...will see if i can come up with some more...
