About This Design
I SOLEMNLY SWEAR THAT I AM UP TO NO GOOD™ T-Shirt
Planning to sneak into Hogsmeade for a butterbeer? Having a midnight duel in the trophy room with Draco Malfoy? Maybe you promised Hagrid you'd feed Fang or teach Grawp some English while he's away. If you plan to sneak out of Hogwarts castle then you'll need to use the Marauder's Map and mutter the words ' I SOLEMNLY SWEAR THAT I AM UP TO NO GOOD™' to activate the spell and bring the map to life! Mischief managed with this fun design of the famous children's book quote from the world of Harry Potter.

Great product just vibe prepared that they are super small and tight, I would order four sizes larger. Has more of a vintage look then a bring image which is cool!

Still waiting delivery for these two items. Hopefully they'll arrive before Christmas.
When ordering I'd not realised they were being sent from Ireland. If I'd known, I would have got them sent directly to those they are gifts for, living in Northern Ireland 😂. Unsure, as hasn't arrived
