Trish McEvoy's eponymous product line started when she noticed that, while there was plenty of makeup on the market, the tools with which to apply it were in short supply. The debut of her top-quality brushes immediately 'swept' the industry and built buzz about her brand—which soon blossomed into a full-fledged cosmetics collection. McEvoy's fondness for function and convenience is evident in signature products like her Little Black Cards, famous for fitting an entire face worth of makeup into a teensy compact. (We're talking credit-card-sized, people.)
