She arrived at the 2019 Tommy Hilfiger and Zendaya runway show in an outfit from the designer, which included a houndstooth blazer and wide-legged metallic trousers.

Her entire look was reminiscent of another era. Embellished denim pieces were popular in the early 2000s, and the newsboy cap has made a recent comeback, with designers such as Coach reviving the accessory.

In January, Hadid wore a leather vest that gave the illusion of a halter top.

The model paired the top – part of Tommy Hilfiger’s collection with Zendaya – with matching flare leather trousers and a shoulder bag from Le Petits Joueurs.

Hadid’s top may have been a nod to the halter neckline that was popular in the early 2000s, but her choice to wear leather-on-leather was also a nod to decades past. In 2019, stylists predicted that outfits with leather would continue to be an increasingly popular trend.

The supermodel attended the Louis Vuitton show at Paris Fashion Week in January wearing a 2000s-inspired outfit from the designer.

Hadid’s outfit included two trends that were prevalent in the early 2000s and are starting to make a comeback: low-rise trousers paired with crop tops.

During the early aughts, many celebrities were photographed in ensembles that looked similar to the Louis Vuitton matching set that Hadid wore in January.

At the Tatras fashion show, Hadid arrived wearing cargo trousers and a puffer vest.

The matching set was from Tatras x Riot Hill’s autumn 2020 collection. She paired the nostalgic outfit with Dorateymur sandals and Jennifer Fisher silver hoop earrings.

In recent years, celebrities and fashion influencers have revitalised the early 2000s trend of cargo trousers – oftentimes with several pockets, zips and strings.

Hadid was photographed in February wearing rimless, ombré sunglasses.

The 2000s saw many styles of sunglasses, including coloured lenses, bedazzled frames and even tiny sunglasses. The latter started seeing a resurgence in 2017.

Hadid sported a furry bucket hat, which she paired with an oversized leather jacket and pinstriped trousers.

At the time of writing, the Ruslan Baginskiy faux fur bucket hat that Hadid wore in February was on sale for US$290.

She accessorised the look with an oversized Stand Studio padded faux leather clutch – that was available for US$3oo at the time of writing in pink and white.

Hadid wore an all-denim outfit to Balenciaga’s Paris Fashion Week show in March.

Instead of wearing a denim dress like Spears, Hadid wore baggy jeans, an unbuttoned shirt with a tan crop top underneath and a US$2,550 Balenciaga denim trench coat that was sold out at the time of writing. She paired it with US$1,190 Balenciaga booties and black sunglasses.

In March, the supermodel embraced the visible thong trend while out in New York City.

Hadid wore US$70 I. Am. Gia trousers designed with self-tie fabric straps, which she wore wrapped around her waist to create the illusion of an exposed thong. The model paired the trousers with a black crop top, a Chrome Hearts leopard bag and US$170 Nike trainers.

The visible thong trend was popular in the early 2000s, and celebrities started wearing it again in 2018. Two years later, it doesn’t seem to be going away any time soon.

The model wore a pair of paisley jeans while in New York City in July.

Not long after Etro released their paisley jeans earlier this year, celebrities like Hadid seemed to embrace the nostalgic style. In July, the supermodel was photographed wearing the US$620 trousers, a yellow camisole, button-down shirt, a Louis Vuitton handbag and US$60 Vans Old Skool trainers.

Paisley jeans are slowly making a comeback, according to InStyle. The pattern, which may conjure memories of childhood, can easily be paired with different colours.

Hadid was photographed during New York Fashion Week in plaid trousers and a long peplum top.

The model wore a black, off-the-shoulder top with a criss-cross neckline. She completed her look with pointy black heels and a sparkly handbag.
