Perfect for every young marauder, this t-shirt features the famous motto in a scrolling banner: “I solemnly swear that I am up to no good." The classic statement is printed in bold, so it stands out from the all over print of the garment which is made up of Harry's lightning bolt scar. Alongside this statement you'll find Harry's glasses, his wand, and footprints echoing from the classic design of the Marauder's Map.

This I Solemnly Swear t-shirt comes in kids sizes 3-10 years.
