Confused about what to wear to work? Me, too. It seems like basic terms like "business casual" mean different things to different people, and we're supposed to magically mind-read to figure it out.
I've learned a lot of hard lessons about dress codes. (Short skirt and midriff-bearing top? Not a great idea. Hey, I was 19.) I pass these lessons on to you in the article: Office Dress Code.
The most important thing to remember is to err on the side of caution. If in doubt, stay well-covered (shoulders and toes included!), and wear clothes that seem, if anything, a little TOO professional. No one will fault you for wearing a suit to a business-casual meeting, but they may look down their nose at sandals and shorts when everyone else is buttoned-down with ties.
