The gift shop portion of the video made me laugh so hard. Ben was looking at the Diagon Alley Spirit Jersey and she said “oh it’s like a spirit jersey”
Brogie, Spirit Jersey is the company that created and popularized that style of shirt. That’s why they are called spirit jerseys. They’ve been around since the 80s & they are not a uniquely Disney thing. Disney, and other companies now, just white label them so they don’t have the Spirit tag on the inside anymore.
I’m sure this is way less common knowledge in the UK as they are an smaller American brand but it still made me laugh because even if you didn’t know that, the shape of the shirt is pretty unique.
