Westward Ho: The Prairie Rose

Hair:
I want to go a little shorter and dye my hair a dark brown or black

Clothes:
I want to get cropped vests and jackets, tunics, leggings, more plaid and nerdy stuff(that stuff rox), I need more bermuda shorts

Accessories:
Maybe fingerless gloves and ties(?)
I was interested in some of this before it became a trend

I’m starting an internship at a large non-for-profit, and while the dress code is business casual and outlines specifics on tops (no shoulders showing, no midriffs, etc.), it doesn’t state much on nice bermuda or capri pants.

So, are like good quality (J.Crew) bermuda chino (at the knee) and cropped pants (mid-shin) acceptable for business casual, if I wear closed toed shoes with — especially in the more humid, spring months? I just cannot imagine wearing slacks when the temp gets above 80.

Thanks!
