If you’re ever wondering what the next big fashion trend is going to be, you can always look to the runways and your favorite celebrities. Often, the two work hand-in-hand, as stars are often the first to get their hands on new designer pieces. Whether they were wearing a fresh new coat, jean, or footwear silhouette, stars set the sartorial standard this year. This year, it was all about chic comfort. 

Stars like Rihanna and Billie Eilish rocked elevated puffer coats seen on the runways at Balmain and Rick Owens, while Katie Holmes and Hailey Bieber were on board with baggy jeans similar to those from Balenciaga and Chanel (goodbye, pin-thin denim!). For accessories, it was all about making a statement and dressing up. Pop stars like Ariana Grande and Olivia Rodrigo loved sky-high platforms for their performances (Saint Laurent, Versace, and Marc Jacobs have shown similar styles), while Kim Kardashian and Gabrielle Union rebuked practicality in favor of small, shapely bags from labels like Gucci and Valentino. 

The most unexpected trends of the year were Y2K-inspired shades (Kylie Jenner's a fan), itty-bitty vests (Bella Hadid loves them), and even dad caps (it may be time to raid dad's closet, says EmRata). Below, read on for the eight celebrity fashion trends that took over 2021.

Small, shapely bags

Forget a tote and go for a bag that only fits your phone, lip gloss, and keys. Miley Cyrus and Kim Kardashian opted for smaller shapes that packed a punch, via angular or boxy silhouettes. Designer styles by Valentino, Balenciaga, and Gucci were a particular hit.

Normcore caps

It was all about the humble dad cap this year. Stars like Justin Bieber, Dua Lipa, and Emily Ratajkowski all finished off their looks with a colorful topper. 

Chunky boots

Celebrities like Cardi B and Selena Gomez stomped around town in boots with hefty lug soles. Many of them offset the clunky shape with more minimal clothing—a smart move, given the heavy footwear adds an instant edge to any ensemble.

Big, baggy jeans

Goodbye, skinny jeans! This year, it was all about the big, baggy fit. Hailey Bieber, Tracee Ellis Ross, and Katie Holmes were all on board with looser fits. Pair them with a tighter-fitting top, or a more streamlined coat or blazer.

Elevated puffers

Yes, puffers can be dressy! Celebrities like Rihanna, Bad Bunny, and Billie Eilish have elevated winter’s snuggliest coat by opting for styles in fun colors and voluminous silhouettes. Just pair it with more sleek, understated clothing.

Itty-bitty vests

As it turns out, a sweater vest and suit vest can be cool. Kendall Jenner, Rosalía, and Bella Hadid have all styled cropped vests in an effortless, casual way—with jeans, shoulder bags, and combat boots

Y2K shades

The breakout sunglasses trend looked back to the 2000s. Tinted (or clear!) shades reigned supreme on stars like Kylie Jenner and models like Anok Yai and Dilone. Pair them with your best Juicy Couture sweats.
