Working in an office means following a dress code for officewear. An understandable necessity, especially if your work involves a lot of face time with clients or colleagues. For many corporate offices, the dress code may range from "business formal" to "corporate casual." And while wearing an all-black outfit or the crisp white shirt will never go out of style, it's still fun to play on fashion now and then. Especially now that the holiday parties and get-togethers are pouring in!

It's been a quite a hectic and tough year for some. Imagine skipping some of those Friday night parties just because you look a little too "corporate" for a fun night out. With the start of the new decade looming, it's time to update your wardrobe with officewear pieces that will take your style up a notch in the office and outside.

Here are our favorite Rustan's exclusive brands that offer business attire that can easily transition from professional to chic party girl.

from Business Meeting to After Party

When you're having back-to-back (-to-back) meetings almost every single working day, it's understandable that there's little time to do a quick touch-up. You always want to look presentable and professional at work but still be the "It Girl" when it's time to be with your girls after office hours. Jazz up your regular business suit with something fun and more in character. Layering is a good technique to spice that boring look.

From working lunch to date night

Look presentable the whole day without even packing for change of clothes. We all know it's always been hard to keep up with date nights, especially if you only wear the typical pencil skirt-and-blazer-suit coordinates. Instead, try to keep your working outfit for the day more special by adding a little flair for romance. Rather than the usual pencil skirt, wear a more flamboyant skirt and wrap it up with something more trendy, like accessorizing it with a big belt or a chic top.

From Phone Calls to Dancing to Dawn

The work for the day will always be tiring and full, with all that demanding phone calls and follow-ups. Don't make it loose your cool and fun spirit. Transcend it to your Monday to Friday work wear, by adding that touch of comfort and jazz with your usual monochromatic look. Try adding complimentary colors and play with structured silhouettes and fun, modern tops. Loose it all on the dance floor and you'll be back again to your usual you.
