The Boy Who Lived Earrings
The "Conveying the Idea of Harry Potter in the Simplest Way Possible" award goes to these earrings. Two circles with a line connecting them, and a yellow zig-zag above it — yup, that's Harry Potter. Simple, but effective. It's a good way to show your Harry enthusiasm, without looking like Luna Lovegood. However, if you do want to look like Luna, there's no shortage of radish earrings, butterbeer cork necklaces, and spectra specs available for purchase at other shops.
