It may be 2018, but that doesn't mean we know about everything in the world.
Whether it be something grand such as new scientific discoveries or a trivial tidbit on what our wrinkles say about us, there's still so much to learn.
We're still being taught incredible facts every day, and one 18-year-old woman from Cumbria, England has recently identified a clothing design purpose that'll blow your mind.
"I learn something new every day."
On October 29, Francheska Horsburgh took to Twitter to share her "discovery" on why some jackets have a button loop on the shoulders.
The teenager said it took her 18 years to figure out the purpose of the odd feature, which is to "hold your bag in place so it doesn't fall off."
"Taken me 18 years to find out that the weird shoulder buttons on jackets is to hold your bag in place so it doesn’t fall off🤯who knew," she tweeted, while including a snap of her red purse held in place under the loop.
The social media post, which has been liked more than 166,500 times and retweeted by more than 67,200 Twitter users, received an abundance of comments, with many people voicing their shock.
"Love Twitter I learn something new every day," one person wrote.
"[I] was shocked but makes so much sense, I just thought they were there for decoration," someone else added.
Another chimed in, "I didn’t know that but I actually do this all the time... thought I was a weirdo but I feel better about it now."
However, other Twitter users took to the social media site to dispute Horsburgh's claim.
The Original Purpose
When some people caught wind of Horsburgh's "discovery," they were quick to dispel her explanation, and shared what the shoulder straps, otherwise known as epaulettes, are for.
According to a handful of Twitter users, epaulettes are a key feature on military uniform shirts, jackets, and tunics to keep a soldier's paraphernalia, such as back packs, ammunition pouches or bayonets from slipping off their shoulder.
So although these loops weren't originally designed to hold your handbag, that doesn't mean you can't use it for that purpose regardless!
But, this isn't the only exciting discovery when it comes to our clothes. For the millions of people who wear jeans on a daily basis, many are unaware why these particular pants have a tiny pocket tucked into a larger one.
Other Design Hacks
Even though it may seem unnecessary to have this minuscule piece of denim, it turns out it actually had a useful purpose when it was created in the 19th century.
According to Daily Mail, the tiny pocket was crucial when it came to protecting a cowboy's pocket watch.
"This extra pouch has served many functions, evident in its many titles: frontier pocket, condom pocket, coin pocket, match pocket and ticket pocket, to name a few," the Levi Strauss website reads.
Now, if you've ever wondered why some clothing items feature sewn up pockets, it's for the sole purpose of keeping your jackets and jeans in shape.
After a few wears, these jacket and denim' pockets will often become stretched out and lose their intended form, making them no longer desirable to the customer.
