10 Fashion Brands TikTok Has ~Officially~ Fallen Madly in Love With

I’m not going to lie — I’ve found myself low-key addicted to TikTok within the last few months (I know, I know, I’m pretty late to the game), but I know I’m definitely not alone. Sure, it may have taken me nearly an entire year just to figure out just exactly what the app was—let alone how to actually navigate through the platform’s endless content —- but alas, I’ve finally gotten the hang of it. This app has led me to discover some of my favorite beauty dupes, life-changing kitchen products on Amazon, and some affordable TikTok fashion brands that I would’ve probably never found left to my own devices.

Sure, a lot of these brand’s aesthetics are more aligned with the viral Y2K trends (i.e. low-rise jeans and butterfly clips) that are all the rage right now — the majority of which, I will not be revisiting — but there’s no denying that these TikTok-approved fashion brands have definitely helped me beef up my summer wardrobe on a budget.

From thrifting to antique stores and even novelty Amazon finds, I absolutely live for a treasure hunt, and every time I open TikTok, I feel like I’m on a virtual one —- enhance the aforementioned fixation with the app. While many of these viral fashion brands and individual products are perpetually sold out thanks to their numerous online endorsements, it’s worth having them on your radar so you can always check for restocks and sales.

Our mission at STYLECASTER is to bring style to the people, and we only feature products we think you’ll love as much as we do. Please note that if you purchase something by clicking on a link within this story, we may receive a small commission of the sale.


Okay, so Amazon isn’t exactly a “brand,” but there are SO many TikTok-famous fashion styles to score on Amazon. For a consolidated list, you can check out their tightly curated “Internet-Famous” hub to find the pieces you saw on the app.

Spirit Jersey

Ever since I discovered this luxe streetwear brand in 2020, I haven’t been able to get enough. The brand has actually been around forever — they’re in charge of all the university and Disneyland merch just to name a couple of claims to fame, but their ready-to-wear collections are seriously next-level.

I got this chic (and super comfy) jumpsuit last year, I can honestly say it’s been the piece I’ve worn most for the past year.

Arguably ~the~ brand responsible for one of 2021’s hottest trends — the crossover waist line — Aerie’s signature crossover leggings and swimwear literally blew up this year on TikTok. It’s been hard for the brand to keep them in stock, so don’t hesitate to get them while you can.

Aerie Real Me Crossover Leggings

Okay, so you may be thinking that $45 is a reasonable price that doesn’t really require a dupe, but the quest for an alternative for this wildly popular pair was brought about because of well, just how popular they became (thanks in part to Tik-fluencer, Hannah Schlenker). They’ve been sold out on and off since last Fall, and while they get re-stocked once in a blue moon, it may not be worth holding your breath for the deal (as amazing as they may be).

I hate this word (but sometimes it’s the only thing that truly fits the bill) but Aritizia’s pieces are unofficially designed for the quintessential “cool girl.” Their selection of premium vegan leather styles has been in and out of stock with regularity thanks to TikTok’s obsession with the retailer.
