I tend to associate dress codes with removing all sense of personal style, but business casual doesn't have to be stiff and boring.
So what if you have a bit of bohemia in you? Make it work, and not just through accessorizing.
When on the hunt for a dark blazer, forget the word 'basic.' Most business casual looks don't leave room for anything exciting like sequins, but subtle details like color-blocked sleeves, a modern silhouette, or contrast piping are simple touchs that show you care just a little more than everyone else.
Knee-length skirt requirement? You won't feel like a gramma in these...
Business casual sometimes doesn't leave much room for color. Instead of bright color accents, go for a strong fabric weave, a little-bit-less-than-A-line silhouette, or just enough of a statement pleat just to make things interesting.
Whatever you do, don't get bored, and be sure to keep your look professional. If your gut feeling is that a certain piece is pushing the limits a bit, don't risk your job over it!
