From 'The Sartorialist' (who else?) is this perfect example of Parisian chic. You simply must read what he wrote (below) about this example of perfect street style because, as always, he is spot on and personally, I love everything about her:
"What a great way to look this summer: so simple and yet so refined.
I love that her shorts aren't too short and that her top isn't too tight. Nothing screams in this look and yet the presentation is very strong.
This is a great example of elegance successfully achieved through understatement and flawless execution."
