Sometimes it's more difficult to dress for a casual day than for a fancy occasion. But Jessica Alba just gave us a spring outfit formula that's more elevated than wearing jeans or leggings. You might not think to wear high-waisted trousers on the weekends, but hear us out: They're just as comfortable yet more stylish. Alba's cool-mom outfit was spotted as she was leaving the Beverly Hills Hotel. Her trousers look just like the Nimin High-Waisted Work Pants on Amazon, which means you can get that effortlessly put-together look, too.
