This is so exciting! Internships are a great way to dip your toe into the professional world, and definitely the time to explore what your business style will be!
I agree with Denise that it’s all about balance and picking one piece to pop while the others play a little more by the rules. I actually demonstrated this advice in a blog post about styling quirky business outfits! We also made a moodboard a few months ago all about playing up nontraditional suit styles, like a shorts suit or a skirt suit (the latter of which is probably more appropriate for your internship!)
