It dwarfs her somewhat width - wise due to her being slim but she's a taller gal; it works out visually.
She doesn't mind through considering she can go out and about while not worrying about purchasing/ finding stuff that she won't be able to carry home on bike. But a downsize would be nice when the price is right.
She originally got it in a clearance/ blowout at our LBS back home; LBS's that serve mostly roadies that carry fixed culture stuff that doesn't move much FTW.
