I have a two-second winter coat hack that you didn't know about, but you need to do before you buy it

TWO friends shared a handy winter coat hack that you probably don't know about, but should.

Before you buy a new jacket, try their quick trick to make sure it actually fits.

Segmedina (@segpugonja) shows random moments from her life online.

While shopping with her friend at the Burlington Coat Factory, she recorded herself trying on different winter coats to test how form-fitting the styles were.

They shared a “coat check” in a TikTok video who knows within seconds.

The basic premise of this is to quickly and intensely roll your shoulders and throw your arms forward to see how confined they feel in the jacket.

“If you see it pull, if you feel like you're going to come out, it's not a seizure,” her friend said in the video.

“The coat check you didn't know you had to do,” the subtitle read.

Her friend tried seven different outerwear items in different colors as part of their trek.

When she wasn't wearing one in the video, she was dancing and playing at the discount store.

She also wrote in the video's caption: “Check your mother f**king jackets.”

Segmedina added in a hashtag that the duo was #friendshipgoals for their funny video.

Many viewers noted that they already knew the fashion hack.

“THIS IS THE TEST I'M DOING,” said one woman.

“I did this test and tore a jacket in Burlington,” admitted another.

“Yes! That's how I test too. They make the shoulder area so incredibly narrow for no reason! And the arm length too,” one TikTok user wrote.

“Why my mom made me do this in Burlington years ago. Let me go thank her,” another commented.
