Step right in folks and behold!
Fez Hat: Don’t worry! There are Stan fez hats out there already made like this one (top picture). Thankfully, it’s made for all sizes as well, so anyone can wear it and the reviews are mostly positive. They also have the first style of Fez (bottom picture) that Stan is wearing during the opening for Gravity Falls so you can choose which style you’d prefer. Fez hats are typically made cheaply as well, so you probably won’t find anything of better quality for that price (I used to work for a gift shop that sold them. N-no… It wasn’t the Mystery Shack!? Or… Was it!?).
Eye Patch: A completely optional piece, you could toss in an eye patch to put overtop of either of Stan’s eyes. Remember that he puts this OVER his classes though. Practically, I’m not sure if it’ll work but give it a shot~ This one here is supposed to be one size fits all.
Glasses: While I’ve seen a lot of cosplay pics of Grunkle Stan that look freakin’ fantastic that used black rim glasses that were all the way around, I really noticed right away that Stan’s glasses actually don’t have a rim around them on the bottom. Instead, they’re closer to these ones here known as an English Warfarer style with a half frame. You can check out pictures in the customer review section also to see if you agree with me that they look a heck of a lot better than these plus they have fantastic reviews.
Suit: Now, a suit by itself can end up costing a lot, especially if you’re looking for a particular one. I tried at first to find a suit with just one button, but the ones I found that weren’t slimming fit were not cheap. You could just put a blazer together with some pants and make a suit, which ends up being a lot cheaper anyhow. Just try to get the colors of black as close as possible when doing this so it looks consistent.
Tie: Grunkle Stan is wearing what’s called a Colonel Tie in a dark red to maroon color like this one here. While the picture isn’t the greatest, the reviews are good. Not only that, but it’s not a clip on and instead goes on with a band, which is probably a lot easier as some of the reviews for another one I found were saying the clip was not working properly.
Undershirt: It’s like… Some sort of conspiracy that a lot of cosplays require a long sleeve dress shirt… Hmmm… I’m sure Dipper would be interested in this kinda thing, but that won’t sell merch in the Mystery Shack so MOVING ON.
Shoes: Grunkle Stan… Really should be wearing black shoes with this outfit. Did anyone notice how much he needs Fashion Advice from Mabel?! Well, moving on real quick before he gets mad. I’m pretty sure that Stan is supposed to be wearing light brown Oxford shoes. You could definitely get a darker color in order for it to match better but… He’s really actually wearing that light of brown.
Alright, now that’s over with… Wait, were those sirens!? Gotta go!
