When I get a new piece of clothing or an accessory that is somewhat out of my usual routine, I usually start out simple when styling it. As promised, the first time I wore my new metallic belt was pretty much exactly like my inspiration picture.
I don't think there's anything wrong with copying things from Pinterest to get a feel for how you'll wear it once you get more comfortable with it. It's also great when you're tired and sleepy and just need a template for what to wear. Go to your Pinterest page and copy something! I'll mix this piece up a bit differently in the future, but it worked well for me on its first outing.
