Trying on clothes in changing rooms can be a marathon - and jeans are the most time-consuming by far.
Whether they're too short, too tight, or too baggy, it's a familiar struggle - but one TikTok user has shared her secret to finding the perfect pair every time without needing to try them on.
According to The Sun, social media star Billie Newland posted a video to her TikTok channel claiming she's figured out a "foolproof" way to find the perfect fit without having to try jeans on first.
She claims you can find the right waist size by measuring the waistband of the jeans against your forearm.
