Nothing puts a damper on your post-work plans like dull office attire. Even though the direction of dress code has shifted from buttoned-up to business casual, we still need to be presentable in the boardroom. But as we all know, shapeless suits and stuffy flats won't get you noticed at happy hour.

In the video above, Style Network fashion expert Sydne Summer transforms one pencil skirt in less than 60 seconds. Start with a flattering lace number -- we're not talking about full-on lace, a single panel detail will do the trick -- and layer with a conservative blouse and pearls. Pretty flats and over-sized bag say "I mean business."

But once five o'clock hits, it's time to loosen up. By wearing a leopard cami underneath your blouse, you guarantee yourself an evening ensemble. Style your work top around your shoulders and switch your flats for some sparkling pumps. A cocktail ring and clutch lets that cute guy at the bar know you know when to mix business with pleasure.
