Today is Victoria Beckham's 39th birthday! When we think of impeccably chic women, we picture Victoria strutting hard in a pencil skirt, sunglasses, and sky-high heels. The fashion lover-cum-designer has nailed her signature style and often leaves us wondering: how does she do it? If you've done your research, as we have, then you'll realize this is a woman with a serious commitment to her look. While there have been undeniable changes in her fashionable aesthetic (like breaking her own no-flats rule), VB never does anything halfway; she rocks it head to toe. Here's a fashion flashback dedicated to her on her big day. Happy birthday to the fashion artist formerly known as Posh!
