No. 3: Leave workout clothes, loungewear at home
Workout gear and loungewear have regained popularity in recent years, but if your yoga pants make their way into your work cubicle, you're going to have a problem.
Loungewear might be fine for the grocery store and running errands (although celebrity fashion experts Clinton Kelly and Stacy London would definitely call it criminal), but it's never acceptable for the office (we don't care where you work).
Even "Casual Friday" should never get that casual.
A good rule of thumb for casual wear at work: If you wear it to the gym or to bed, you should never wear it to the office.
We fully support stopping at the gym on the way home from work, but you'd better need to change your clothes!
Our next tip is based off the idea that less is more ...
No. 2: Keep accessories, makeup to a minimum
Unless you're part of Lady Gaga's entourage, your work wardrobe shouldn't contain wacky accessories or costume pieces.
For the office, keep accessories and makeup to a minimum. Some industries, such as fashion or beauty, may allow for more experimentation with trendy looks, but most require a more sophisticated approach.
Avoid jewelry that is overly loud (physically or visually), and (unless you moonlight as a clown) keep your makeup subtle and classy. When it comes to makeup for the workplace, think "old Hollywood glam" at the very most and never ever venture into punk rock for the office.
If you want to look appropriate and trendy, make sure your accessories are not only sophisticated but also in season.
Finally, take some advice from fashion icon Coco Chanel and "before you leave the house, look in the mirror and take one thing off."

No. 1: Rethink that skimpy outfit
What's the No. 1 rule of thumb for what not to wear to work? If a stripper would wear it to work, you shouldn't (unless of course you're a stripper).
Sure, modern fashion trends have made it acceptable to wear a lacy camisole under your blazer, but anything too revealing should never be worn in the workplace.
Just because Erin Brockovich pulled it off doesn't mean you should give it a try. Keeping your bits covered isn't just about making your office mates more comfortable; it can also potentially ward off unwanted advances. (And who has time for sexual harassment suits these days?)
