If you’re one of the 50 million people who watched the simplynailogical videos putting on 100+ coats of nail polish, then you know nails can get pretty out of control. Well, we decided to take the 100 layers challenge idea and kick it up a notch by trying to apply 1,000+ layers of nail polish to a hand. Can it be done? Can we make nail art pretty enough to go viral on TikTok? Will HopeScope end up reacting to this “satisfying” creation? And will we reach the top of #PolishMountain? Today, loyal Theorists, we find out in this ultimate nails challenge!

Are caffeine skincare products worth it? Like, do the serums, scrubs, and facemasks actually give you as much energy as, let’s say, a Diet Coke, Monster Energy, Red Bull, or even coffee? Are you actually absorbing that energy through your skin? We put our caffeine addictions to the side to first go caffeine free and then test a new skincare routine. Just like Mia Maples loves to do with viral TikTok products and HopeScope with satisfying viral products, we’re experimenting with a whole new routine that could change the way we take care of our skins… or it may just be a bunch of bunk!

After seeing the fun videos full of fashion inspo from Ellbat (I Hired a $200 Stylist and $20 Stylist to Dress Me for a Week) and Mia Maples (I Hired 3 Stylists with Different Aesthetics to Style Me), we’ve decided to test the world of online personal stylists for ourselves. Today we’re testing Fiverr vs Stich Fix to see if any of these digital personal stylists are worth it. What is the cost? Can Ai really determine what we should wear? And can we actually find a new look in this process? C’mon, get ready with us as we try on a whole new wardrobe!

Which skincare products do YOU use, loyal Theorist? Neutrogena? CeraVe? Cetaphil? Pond’s? Well, you may want to take a CLOSER look at the label. It turns out that the skincare industry may have been lying to us for years about what’s really hidden inside of their products. Sorry, Mia Maples, but you may think twice before doing about skincare test video because this could change your daily skincare routine FOREVER.

The countdown begins, loyal Theorists. This is MatPat’s FINAL Style Theory ever. We knew we had to go out with a BANG!

Grab yourself a bow tie and let’s suit up!

Hello, loyal Theorists, and welcome to Amy’s FIRST Style Theory! Today we’re diving back into our favorite Style Theory setting: the bathroom.

Well, by the end of this video, we promise that your legs will be perfectly silky smooth!

If you watched the Super Bowl, then you saw a whole lot of Travis Kelce, incredible coverage on Taylor Swift, and a very questionable ad on Temu. You probably remember the ad well, right? Temu: shop like a billionaire. It played, like, 500 times throughout the game. But can you _actually_ shop like a BILLIONAIRE on Temu? If FaZe Rug, HopeScope, Mia Maples, and the hundreds of other YouTuber videos have shown us anything about the brand, the answer is a strong NO. But we had to find out for ourselves. Will we walk around looking like tech moguls Elon Musk, Mark Zuckerberg, and Mark Cuban? Can we strut in a dress as expensive as Taylor Swift’s? Or will the Temu dupes make our space look like Kim Kardashian’s Sknn office decor with a bunch of Donald Judd dupes? C’mon, loyal Theorist, let’s shop like billionaires!

Have you ever thought, “why do I look bad in everything?” We promise, you DON’T! But one factor that could lead to you feeling that way is not dressing to your body shape or body type.

AND then we’ll teach you how to dress no matter the shape of your body: rectangle, pear, or inverted triangle. Let us know your shape in the comments below!

Is your closet a MESS, loyal Theorist? Are your clothes all thrown about with no rhyme or rhythm where they should be?

So we're following the footsteps of Mia Maples and decluttering YEARS worth of clothes. This is going to be one intense closet clean out!

Theorist, does Gen Z look older than other generations like Baby Boomers and Millennials? Everyone on the internet seems to think so thanks to TikToker Jordan Howlett. But is it even true?

WHY is Gen Z aging so rapidly? Today we find out.

You've been asking for months, loyal Theorist, and today we finally answer: which clothes would help you survive a nuclear apocalypse? With Fallout on Amazon Prime making waves in the cultural conversation, we knew we HAD to answer the question for you. Do we need super high-tech survival gear? Or can we just wear jeans and a t-shirt? Let's find out...

Your favorite influencer may be turning into Ai... No, we're not talking about Vtubers, we're talking about companies like Meta turning creators and influencers into Ai chatbots. From MrBeast to Kendall Jenner to Charli D'Amelio to Tom Brady, they've all signed some Ai rights over to Zuck. But what exactly are the Ai creators like Kwebbelkop, Lil Miquela, and others doing? How are they making money? And is ANY of this good for society? Today, Theorists, we talk about a very controversial topic...

Are crocs truly the ultimate active footwear? After seeing @hopescope test out _every_ single Croc, from survival Crocs to Crocs ballet flats, we knew we had to try them out. Millennials started wearing Crocs as an everyday shoe, but Gen Z and Gen Alpha have taken it to the next level. Some members of Croc Nation, like Ash of @GTLive , are actually wearing Crocs to the gym! That's sport mode on a whole other level. Today we're going through a whole series of tests to see if Crocs can _really_ walk the walk.

What do they ALL have in common? A link back to anime. In this video we'll reveal the secret influences of Dragon Ball Z, Sailor Moon, and more on our culture.

A few weeks ago, creator MiaMaples posted a video called "Temu Stole From Me," where she explained how the company took her name, image, and likeness to promote and sell a product. Sounds kind of familiar, right? If you've followed Style Theory over the past year, you'll remember our video about how SHEIN did something similar to Cassey Ho (@blogilates) of POPFLEX. If you follow @hopescope you may know she's posted multiple videos buying brands that stole her videos for ads. She was able to poke fun at the matter, whereas creators like Cassey, Mia, CassandraBankson, and simplynailogical all made more serious videos discussing the unfortunate topic. So what's the deal with these shady business practices from SHEIN and Temu? What happened and how do they keep getting away with it?

The Olympics have been SO fun to watch, haven't they, Theorists? Watching Simone Biles soar to gold in women's gymnastics, Caeleb Dressel rake in the medals in men's swimming, the USA women's rugby team shocking the nation, and every other Olympic athlete has been an absolute thrill. But, one thing that we questioned was just how optimal their uniforms are. Is there a better way to win gold?

We're using different Vacation sunscreens, such as gel, spray on, stick, and even milk (ick). Who will WIN this sun screen test? Watch to find out!

Picture this, loyal Theorist: you just spent your well-earned money on a brand new, sparkling clean, white pair of Nike Air Force 1s.

Loyal Theorists, if you're a lover of spooky season and the Halloween spirit that comes along with it, then you're very familiar with witches. Think of the witch that comes to mind. Is she green and crooked-nosed with a pointy hat like the Wicked Witch of the West? Or is she more modern with cute clothes like Scarlet Witch or Agatha?

Theorists, can certain outfits and accessories help you feel less stressed and anxious? If you've been scrolling TikTok recently, you may have seen the viral Comfrt hoodie, which is supposed to help you care for your mental well-being. It's smooth, it's soft... but does it work?!

Wicked is absolutely dominating the box office right now, and with good reason. It's an absolute bop. Ariana Grande, Cynthia Erivo, Jeff Goldblum, and the rest of the cast crushed it. But I left the theater with one question: why is the witch green? And could you or I turn green in the real world? What would that take? It's time to defy gravity with this theory...

Today we put oopsie clothing through a social experiment.
