Although matching sets are a quick option for cozy fall days, they’re a bit overdone.

“Instead of reaching for the matching set, be prepared with a ‘personal uniform’ — something quick that you know looks good on you,” Mason Miller, a fashion designer, told BI.

Gen Z pioneered matching sets, influenced by Y2K brands like Juicy Couture. But over time, the creativity ran out, and Miller said they’re being deemed basic and boring.

Instead of reaching for a puffer jacket when the weather cools down, stylist Susan Mammadova suggested stocking up on longer trench coats.

“Puffer coats are out,” she told BI. “The oversized, layered trench is set to be major after it gained traction last year.”

The shift to a fancier silhouette is in tune with the move from “hypebeast” street-style clothing to the “clean-girl” aesthetic.

The stylist said leather trench coats, in particular, will be big because they can easily be dressed up or down.

Turtleneck sweaters have been around for a while, but it’s time to opt for a neckline that’s more comfortable, according to Safeyyah Aly, owner of Your Friend Sabo.

This fall, go for looser cowl necks or a simple, round neckline.

With aesthetics like indie sleaze back in style, DIY-cut necklines are another way to match the current trends.

If you fell for the cheetah- and leopard-print craze, unfortunately, Miller told BI the trend is coming to an end.

The designer said zebra-printed clothing had a similarly quick rise to fame and decline in 2020.

“If you want a bold, fun look, try finding a different print, even if it’s not animal,” he told BI. “But this one is totally overdone.”

Mammadova said big earmuffs are dying out in favor of more elevated pieces to keep your head warm.

“Earmuffs used to be a favorite, but since that’s overdone, I think variations of hoods will be the must-have fashion accessory this fall for a unique twist,” she said.

The stylist said the new trend is riding the heels of the resurgence of balaclavas last year.

Overalls have been in and out of fashion since the 1990s, but Aly thinks it’s safe to say they’re out again this fall.

“Let’s leave them in the past,” the designer told BI. “Unless styled uniquely, the style seems super outdated and a bit boring compared to other trends.”

In general, ‘90s-inspired clothing is starting to be replaced with more 2000s and 2010s styles, like skater skirts.

Flats have become hugely popular, but Miller told BI that mesh designs are falling out of favor.

“The mesh has gone too far,” he said. “Get a normal ballet flat or thin loafer because I think thinner shoe silhouettes are here to stay.”

According to Mammadova, maxi skirts are being replaced by miniskirts — with a twist.

“Mix unconventional pieces, like wearing jeans under a miniskirt or layering in other creative ways this fall,” she told BI.

The stylist said the trend aligns well with the rise of more sustainable capsule wardrobes since shorter skirts can easily be worn year-round.

Boot brands like UGG had a major resurgence this time last year, but Aly said the wave won’t carry into this fall. Although the fuzzy-lined boots are nostalgic for some, they lack individuality and creativity.

“I think we should just steer clear of sticking to simple trends like these,” she told BI.

Beyond wearing UGG slippers in the house, the aesthetic is being eclipsed by motorcycle or “moto” boots, especially from brands like Doc Marten and Steve Madden.

Studded, punky accessories reminiscent of 2016 fashion had a bit of a moment, but Miller said people are already over the recycled trend.

“I can already see studded jeans crowding racks at thrift stores,” the designer told BI. “If you want to achieve that rock-star look, learn how to layer and play around with different silhouettes.”
