I'm a professional stylist. Here are 9 pieces of clothing you'll probably regret buying.

• I'm a professional stylist, so I have a sense of what trendy clothing items aren't worth buying.
• Chunky, colorful slides and sneakers aren't the most versatile footwear options.

Fashion is a creative tool for self-expression, but trying to keep up with every trend can be costly and time-consuming — plus it can leave you with purchases you regret.

But as a professional stylist, it's my job to keep track of what trends are worth investing in, as well as which ones aren't.

I'm not a fan of Adidas' Yeezy slides and their knockoffs

Ye, commonly known as Kanye West, has had a clear influence on fashion, but I don't think his line of Yeezy slides are worth buying.

I've tested a few knockoffs and have even tried on the real deal in the store to figure out how to style them but am still not sold.

I thought colorful slides would offer fun nostalgia, but these may be better as casual house shoes.

Neon 'dad' sneakers aren't a versatile footwear option

Chunky, brightly colored "dad" shoes can make an impact, but you might not want to invest in them.

For example, even though they're cool, Balenciaga's triple-sole neon-green sneakers cost over $1,000. They don't seem versatile enough to become a wardrobe staple that's worth your money.

They are also too big — the sneakers meet you at the door before you see the person wearing them.

The leggings that got famous on TikTok had a good run but aren't worth buying now

Several leggings got popular on TikTok for being comfortable and accentuating your bottom. I jumped on the trend and wore them to shop, work out, and lounge.

But eventually, I regretted my purchase. There was always someone in the same pants as me, so they lacked the originality I enjoy.

Large Gucci belts can come off as overly flashy instead of classy, in my opinion

Even though Gucci belts with oversized emblems may have their moments, I wouldn't recommend buying one.

The belt costs hundreds of dollars, and I bet it'd spend most of its life collecting dust in your closet because it won't go with every outfit.

Tiny sunglasses are too small to be of any use

Even though they're trendy, tiny sunglasses aren't functional. Some aren't even large enough to cover your eyes.

I'd have to squint out of the frames to see where I was going, and they didn't even block most of the sun's rays.

Micro bags also lack function

Micro bags may be a convenient, portable option, but they barely hold anything.

I bought them in a variety of colors but was mainly left with regret.

They could barely fit a pack of gum, let alone my essentials. I often just ended up carrying another bag.

Despite making a fashion comeback, wrestling suits aren't very chic

As a one-piece outfit, wrestling suits are easy to pack and accessorize with a belt, corset, or some jewelry. But I don't think everyday wrestling suits make for the most fashionable choice.

Every time I see anyone wearing one, I immediately think of John Cena in the ring. I don't see them aging well.

Cross-body fanny packs are convenient but can look lazy

For a while, when I had to dress a client, I'd immediately grab a fanny pack. The trend looked effortless and the bags are easy to find.

I'd even use one as a clutch for day outings.

But at the end of the day, you don't need to dive into the trend and get a fanny pack in every color and style.

Bike shorts hardly ever look original

Bike shorts are a 1980s trend that has made its way back into the fashion world.

They can be an affordable staple for day looks, especially paired with an oversized shirt and sneakers.

However, don't invest in them to elevate your closet, as they lack individuality and are difficult to dress up in an original way.
