Have you ever woken up on a Monday and not wanted the weekend to end? Well bring your weekend style into the work with you. Just grab your favorite plaid shirt, in my case it would be this great plaid from J-Crew and pair it with a crisp pencil skirt. The key to professionalizing this look is to keep the silhouette as sleek as possible. Tuck it in to create a cleaner, more buttoned up look. Play up the shirts colors in you accessories to tie the look together. P.S. For the real detail oriented professionista, match the metal in your jewelry to the hardware on your bag.
