What do you get when you bring together one of Britain's most well established retail moguls and the undisputed queen of modern American music? Atlanta is about to find out as Arcadia Group and its chairman Sir Philip Green and Beyonce have come together to co-found IVY Park activewear. The brand made its official debut at Nordstrom at Phipps Plaza on April 14.

The 200-piece collection with sizes ranging from XXS to XL, includes a variety of t-shirts, tank tops, hoodies, shorts, caps, footwear and what might be the most impressive and popular piece of the collection, leggings. The IVY Park leggings will come in low-rise, mid-rise and high-rise styles to better accommodate the athlete in every customer. The leggings also feature inner contour shorts for an added comfort. The "V" Mid-Rise and Linear Print V-Waistband Capri leggings ( both $62) are two options available at Nordstrom and online.
