What they wore: A gray, red, yellow, and black Boom! sweatshirt from the 3.1 Phillip Lim for Target line, retailing at $29.99.
When they wore it: The "Fantastic Four" actress hit the launch party for the affordable line during New York City Fashion Week on September 5. The hotel heiress took a weekend bike ride through the Big Apple on a Citi Bike two weeks later.
How they styled it: Hilton donned pedal-friendly red flats, light wash jeans, and red sunglasses for her sunny ride. Alba punched up her casual look with red pumps, navy silk pants, and a black satchel.

Judge's scorecard: Alba typically blows the fashion competition out of the water, but we're giving this one to Nicky. A sweatshirt doesn't need to be dressed up and works best with a simple pair of jeans.
