Billie Newland’s viral TikTok video of how to do it may have made shopping for jeans a lot easier.
The 25-year-old says she discovered the hack while doing laundry and it involves using your forearm to find the ideal size without ever trying the jeans on.
In her video, she says to measure the waistband using the length of your forearm from your elbow to your wrist. If your arm fits snugly inside the waistband, that’s your perfect pair.
To test her theory, she asked her dad, boyfriend and friends to try the hack out and they all confirm it works. It could also help you find the right fit for shorts or skirts, too.
