This jean hack is going viral for helping you find the 'perfect fit'- but does it work??

Find your perfect jeans fit... with your arm?

It's pretty safe to say that finding the perfect fitting pair of jeans is almost impossible- but now Tiktoker Billie Newland is sharing the ultimate hack to fix that!

She explains; "Choose a pair of jeans and stick your arm inside the waistband. If there's a large gap between your elbow, your hand and the end of your jeans then they're too big.

"On the flip side, if your [forearm] doesn't fit inside the waistband then they're too small."

If you can fit your forearm and hand inside the waistband and it's "completely snug", then those are your "perfect pair".

But the internet is NOT convinced...

"But what if you have a tummy??" one user commented on the clip.

Others said their bodies were "too disproportionate" for the hack.
