Just a few months ago, experts predicted Jessica Simpson's clothing and accessories empire to earn $1 billion by the end of 2011, and turns out prom is part of her big plan! The singer recently released a line of special occasion and prom dresses, and the lineup includes strapless black gowns, purple tiered dresses (shown), and patterned one-shoulder looks. The six-piece collection is available now on for $139 to $229.
