You know those not-so-fresh days? Even I have moments of style slaking when I really just want to run my errands in a pair of Chucks and an old hoodie. However, I have a reputation to upkeep. Not that there's anything wrong with dressing casual, it's just a disgrace to my collection of 24/7 flats. Meaning flats that are so fabulous they work around the clock, because of glam details like rhinestones, glitter, and pearls. As this week's Life&Style points out, even divas-in-the-making like Rihanna tone things down with a pair, but not too much. Really, all you need is a white tee, an easy-going pair of jeans and you're stylish — 24/7.
