As co-owners of an LA event company, Marissa Mills and Lisa Present noticed the celebs they worked with were addicted to shapewear. And as regular gym–goers, they noticed that most workout wear made even the fittest women look frumpy. With the fusion of those two savvy observations, Style Firm Los Angeles–a line of fashionable, functional, firming fitness wear–was born. Designed to let busy women go seamlessly from Pilates to post office, it'll have you looking svelte before you even break a sweat.
