The way you wrap your scarf could reveal if you're a millennial or Gen Z

• The way you wrap your winter scarves could reveal what generation you belong to.
• TikToker Noah Altink says millennials wrap a single knot, while Gen Z does a double-end loop.

Skinny jeans aren't the only fashion choice revealing your age.

According to TikToker Noah Altink, how you wrap your scarf can also show whether you're a millennial or a member of Gen Z.

In a video posted on December 2, Altink showed two ways that people commonly wear the winter accessory.

He said millennials seem to favor a single knot method with their scarves hanging in a line down the torso, while Gen Z typically creates a loop with both ends of their scarves hanging side by side.

His TikTok video has since gone viral, having been viewed more than 4.2 million times as of Thursday.

While some TikTokers said Altink was spot-on with his side-by-side styling video, others disagreed.

Some members of Gen Z said they typically skip wearing scarves, even when it's cold out.

That could be because the unofficial Gen Z uniform — baggy crewneck sweaters, flare leggings, and UGG boots — is pretty warm on its own.

Others said a person's generation has nothing to do with how they wear scarves. Instead, they argued that people simply wrap their scarves however they see fit to stay warm.

If you also disagree with Altink's video — or if you just don't wear scarves often — there are other simple tests you can do to see which generation you fall more in line with.

As podcast host Phoebe Parsons said in a November TikTok video, your socks are another tell.

She said millennials typically wear short ankle socks, while Gen Z opts for taller ones.

Hand gestures are also different between the generations, according to a TikToker who goes by Ludny.

In a video posted in late November, Ludny showed that millennials use both hands to make heart shapes.

They also mimic landline phones if pretending to take a call, and they pretend to be holding a digital camera when using their hands to show how they'd take a photo.

Gen Z, on the other hand, uses four fingers to create heart shapes, they mimic iPhones when pretending to take a call, and they pretend to be holding their cellphones when showing how they'd take a photo.

Generations, of course, are determined by birth year.

Millennials were born between 1981 and 1996, and Gen Z was born between 1997 and 2012.

But after taking these tests, you might find yourself confused about which generation you actually fit in with.
