Designing bags is a family affair for sisters Bridget and Megan Torregrossa. After working in public relations for four years at Burberry (Bridget) and graduating with an accessories-design degree followed up with an internship at Ralph Lauren (Megan), the siblings launched a capsule collection this past January. Named Torregrossa, it was picked up exclusively by the Plaza Shops in New York. Now, for fall, they’re expanding with eight new styles, such as square flap front clutches in purple or green crinkled leather, as well as small leather goods, including wallets and makeup bags. The line wholesales from $100 to $635, for an exotic python-skin bag.
