We just had one of those 'aha' moments, and thought it'd be rude not to share. It's a Fab fact that Olivia Palermo gives us a serious case of outfit envy every time she gets snapped, but we've figured out why she always look so darn good. It's all in the shoes! Take a gander at the pics — cute outfit yes, but the shoes make it every time.Olivia's got a knack of upping the wow factor of a simple, monotone outift by teaming it with a knock-your-socks-off pair of heels. This has got to be the easiest trick in the book, so we rounded up some of the best stand-out heels, so you can trick up your look just like Liv. Happy shopping!
