Today, the adorable fashion prodigy, whose real name is Sydney Keiser, and her mom Angie appeared on "CBS This Morning" to talk about the 4-year-old's creative process and her upcoming summer 2015 crewcuts collection. In the segment, we learn that Sydney likes to design dresses for both herself and her "imaginary sister," a pint-sized mannequin she calls Mackenza.

And, we can't help but marvel at the little girl's work ethic. "I practice a lot," Sydney tells the reporter, estimating that she dedicates about 10 hours a day to her design work (though we're guessing the 4-year-old hasn't fully grasped just how long an hour is... )

Way to go Sydney!
