3. Dated shirts

The dated Disney shirt is one of the strangest articles of clothing in existence. And yet, they sell very, very well. Every year you return to Disney, there they are – reminding you, in case you forgot, exactly what year it is.

It's hard to imagine wearing these shirts in any other environment as an adult. Sure, they seem right at home on Main Street USA, but where else could you get away with that vibrant of a graphic?

Yet, it's easy to be seduced by the dated tee because, ultimately, they are not about fashion. If you buy one, you aren't doing so in order to look fashionable, or because you think it'll go with that pair of pants you bought just last week. It is, perhaps, the perfect definition of a souvenir: it serves no real purpose other than as a memento of a vacation you've loved.

It has the words “Walt Disney World” on it: Proof that you were, in fact, there. It has the date on it: Reminding yourself, years from now, when exactly you visited. It has a fun, graphic design on it: Recapturing the feeling you had when you bought it – one of magic and mirth.

If you buy the dated shirt, you aren't doing it for the purpose of wearing it. You're doing it for the purpose of having it. Just to have, look at, and remember.

But the promise of that memory is enough to make you fork over the dough, at least once. Trust me.

2. Pins!

Some of the most idiosyncratic and unique designs in all Disney merchandise can be found on pins. Somehow, against all odds, these strange little accessories have become the place to go if you want something that will last, be different, and is themed to a specific attraction or resort.

The idea of pin trading – the custom Disney introduced in the early 2000s – will likely lead you to buy a starter lanyard, and from there, it's a slippery slope to individual attraction pins, special event pins, and so on down the line. Some collectors have thousands. Others just buy one or two.

But even if you don't want to trade them, pins can be tough to resist. They can remind you of an old attraction that has since been removed, or your favorite spot that's still around. They feel substantial, and you know they'll age gracefully.

Even if you only buy one, realize you have nothing to wear it on, and store it away somewhere safe, you will likely find one that you just have to have. There are so many, and they're so unique, there's certainly one that will tug on you in the right way and wind up back home with you.

1. Mouse ears

If you don't buy a pair of mouse ears at least once, why are you even at Walt Disney World? I mean, really! They are so iconic, and they've been around for so long, there's a habitual purchasing-instinct that I believe has become coded into humanity's DNA over the past half-century.

And, even if you aren't interested in the classic Mickey Mouse Club-style, Disney has you covered. Do you want a headband with mouse ears? Disney has it. Do you want mouse ears, but in the style of Sorcerer Mickey? Done. Do you want special wedding themed mouse ears? Graduation? R2D2? Done, done and done.

There's a memetic quality to the mouse ears that is inescapable – i.e. you see them all over, and you see everyone else wearing them, so you just have to buy a pair to fit in. Maybe you won't wear them ever again, but while you're at the parks, you feel like you're finally wearing the right attire.

After buying them once, you probably won't do it again. If you return to Walt Disney World, you may not even bring them back with you. But wearing mouse ears and walking down Main Street USA is just part of the shared human experience now.

And for $15, what a bargain!
