Sportswear is made simple with these two easy pieces when they are accented with just the right accessories. We love the ease and elegance of these white wide-leg trousers by Ellen Tracy for Macy's, $79.50, and Lucca Couture classic tube top from Apotheca Salon & Boutique, Bethlehem, $50, with its super-skinny red and white stripe—so perfect for lunch on the patio. Katie carries her Rebecca Minkoff Whipstitch satchel leather bag, $525, and wears a Rachel Reinhart necklace, $195, both from BOUTIQUETOGO. Her INC International Concepts Mariela Mary Jane peep toe pumps are available at Macy's, $89.
