Katie Holmes Suri Cruise

Suri Cruise is NOT wearing a dress ... say it isn't so!

With mama Katie close by, Tom's little girl ... wearing adorable shorts and flats, hung out with mom on the set of her new movie Jack and Jill in Beverly Hills.

The 4-year-old, who is already considered a pint-sized fashionista, definitely has a passion for fashion.

Loves it!
