Depending on where you work and what you do, the dress code may be more limiting or you may get to wear whatever you want. As a consultant, the rule of thumb is to dress one level above your client. For me, that usually means a sheath dress (easy breezy) or trousers and a nice top. One way I like to punch up the formal factor in my work wear is with a blazer. The common colors are black, navy and gray. I’m loving all three of these for a creative kick. Which one speaks to you?
