From now until Valentine's Day on February 14, StyleBop.com is offering its discerning clientele the opportunity to add an exclusively-designed Valentine's Day card to their order for no extra charge. The cards are particularly special as they have been created by designers Mary Katrantzou – who was recently announced as one of the seven finalists for the BFC/Vogue Designer Fashion Fund – and Roland Mouret.
