Victoria Beckham Wearing Leather Leggings and Spring '12 Dress

Since the Spring '12 runways, we've been waiting to see which celebrities would wear the looks first — but it's a special treat when the designer wears her own clothes. That's exactly what Victoria Beckham did at last night's WWD's Apparel and Retail CEO Summit at NYC's Plaza Hotel wearing a strapless colorblocked dress over leather pants from her Spring '12 collection. Get this: those leather "pants" are actually leather leg warmers (clipped into her Louboutins) to emote the dress-over-pants trend we saw all over the Spring collections. Now with a glimpse of the runway to reality, we're even more convinced of its cool effect. Sure, the style requires a little risk taking, but if you're game, just read on for our styling tips then shop the pieces to try the look for yourself.

• Choose pieces that flatter your shape. You don't have to wear a body-hugging strapless and leather leggings a la Victoria to wear the trend. Opt for separates that flatter your figure.
• This look works best when you keep your dresses and pants proportional. If you've chosen a loose, billowy dress on top, look for pants that stay a little more fitted to the body so you don't lose your shape.
• This is a contemporary look that's meant to be easy; a dress with too much length or bulk is going to feel overworked and off balance with the casual vibe of the pants you pair with it.
• Embrace the trend now with this season's sweater dresses and knits over slim pants and leggings. This may be the easiest and most universally flattering way to wear the look.
