Nicole Richie Changes Outfits Four Times in One Day (PHOTOS)

Not only was Wednesday a busy day for Nicole Richie, but her wardrobe got a workout too.

The Fashion Star judge was seen in not one, not two, but four different looks, as she made appearances all over the Big Apple on Sept. 12 to promote the launch of her limited-edition collection for Macy’s Impulse.

Where did she go –  and more importantly, what was she wearing?

Richie, 30, began her wardrobe whirlwind in a floral kimono-like number and two-tone pumps, as she headed to the Good Morning America studios to promote the new line.

Although Richie stuck with the Geisha-esque top knot she arrived in, the rest of her look was fleeting: The fashionista slipped into a peacock-printed dress from her Macy’s Impulse collection for the interview.

Breaking up the blue-green palette she rocked most of the day, Richie was all business in a taupe shirtdress, as she headed to a meeting (though she was later spotted ducking into Barney’s, perhaps to pick up a few accessories to go with her fourth and final look).

Finishing off the style parade at Macy’s to celebrate the launch of her collection, the mother-of-two was all smiles as she greeted fans and posed for photos. Sporting a long-sleeve velour frock and purple open-toe clogs, the designer embodied the boho-chic style she had in mind when designing her capsule collection for Macy’s.
