JEAN SHOPPING HACK - find jeans that fit without trying them on! 1. First, find the right size by selecting a pair that wraps around your neck. Then they will fit you close to your natural waist/ right around your belly button. 2. Find the right length. Hold one jean leg in each hand. Extend your arms. If they extend all the way, then the jeans should stop close to your ankle. If your arms don’t extend all the way, the jeans will be cropped. If you have more Jean leg, then you have arm span, you’ll need to wear heels. you can use this trick when you’re shopping without a soft, tape measure and your fit quiz results from Jen’s Jean shop on closetchoreography.com. That’s how I found the jeans that I’m wearing in this video.
