Mark Fischbach as The Convict Simon

I sure do! Sorry this took me a week!

Note: I do not have access to the official costume guide due to being a brokie. I spent many many hours scraping and eyeballing this.

Simon Full Costume / Outfit Breakdown + Reference Images

Hood

Fun idea! Simon's hood was originally white, most likely. I'm sure these guys either bought this piece pre-distressed or they did it themselves.

This is a good starting point, but it would need to be modified:

Tunic & Pants

These are art pieces and practically unobtainable. This is probably going to be a "make it yourself or close-approximation" scenario.

Detail note: Simon has a black re-fitting seam on his pants, meaning they got too small at one point. This was also part of the original pants design, but I personally like the idea he's had to repeatedly "grow" out of his clothes.

Knife Sheathe

That little rounded cut in the middle of the leather really threw me, but I found it! Took me an hour and a lot of yelling at Google Lens.

This is Simon's other knife holster (the one on his back that everyone has been struggling to find photos for, even me!) I was blessed with this knowledge by a friend who has access to the style guide.

Belt + Pouch

Pouch. I was also gifted this knowledge from someone who bought the style guide.

The Harness™

Scrolling through kink gear to find this was a trip and a half. I've been blursed with some foul knowledge. Holy hell.

Yeah, by the way, this is actually, officially kink gear. This is not a bit. This is not a joke. It's kink gear.

Do with that what you will. I'm just the guy who told you where to find the harness. *my voice fades away into echoes*

Boots + Spikes + Gaiters

I've seen some people recommend these:

But I'm actually more inclined, personally, towards different, because his boots are olive green with a lighter sole. I can assume the color of the actual boot is lighter as it's supposed to be well-worn in the movie.

There's a really chunky high-arch, and it appears he's got some spikes on the boots. It's kind of cowboy-esc. There's a high-chance these are no-lace tanker-style military surplus boots. I'm sure these costume designers chose some weird unobtainable brain of hyper-niche shoe or some shit, so... yeah these are definitely shoes meant for armored vehicle operation. They don't have laces because they'd get caught in machinery (or at the very least, the laces are covered with a buckle).

These are kind of a rarity, so here's a random Ebay listing of military tanker boots in a similar color:

Corcoran Men 10" Coyote Tanker Military Boot CV2600 *Made In USA* Tan Size 6EE

Here's another close-contender option. I like the stripes on these.

I noticed there aren't any spikes on Simon's boots, so I went with a rubber / mildly studded version. It's got similar strap patterns. I bet you these were used so Markiplier didn't eat shit on-set. In a canon way, though, I wonder if these were his, or if the COI issued them for labor purposes. I wonder what they did with the spikes they pulled out.

These were NOT hard to find on Amazon. They're snake gaiters!

Headband + Gloves

I originally assumed that the headband was sweater material, but after something akin to critical thinking blessed me, I realized they used a hat (I caught onto this from the tunic reference image from Demobaza! Simon had a beanie at one point before he broke it down into a headband). So, grab yourself a beige beanie and snip that thing!

I think these are just some nondescript wool gloves, honestly. Here's a close contender:

Addendum Inference

People from Iron Lung hoard their belongings on their person. If you want to add depth/detail to your Simon cosplay, put trinkets/ties/similar things to the headband scrap cloth on him. It's okay if they're not from the movie! He's a hoarder.

Simon is a soldier. Almost everything he has is military-issued. He wears a lot of tactical items and once carried multiple weapons on him, not just the knife from his mom.

Dude's a freak on the down-low. There are no excuses.

If you end up buying shoes with laces on them, pull them out and use them for other things. The smallest details matter. That man would see a shoelace and see a million uses for it.

The headband is also his hair tie.

His clothes have been refitted at least once.

Happy pride month! Alt under cut
