Harry Potter Out of 10 T-Shirt

We may not know everything about everything in the Potterverse, but we’re pretty reliable most days. We’d rate ourselves a solid 9 3/4 out of 10, because even we have our off days and can’t remember the name of Voldemort and Bellatrix’s child sometimes. (It’s Delphini, by the way. We looked it up.)
Let everyone know that your knowledge of Harry Potter is as flawless as Hermione’s pronunciation of Leviosa with this black, 100% cotton shirt. Machine was cold. Tumble dry low. Imported.
