To show your figure at its best, you should make sure you go for jeans with a higher waistband. This makes your hips appear higher, making your legs look longer and balancing out your body proportions.
Try to avoid paints with cuffs and ¾ length. Long length pants are better. Jeans with a straight leg or bootcut jeans are ideal. They make your legs appear longer and slimmer. Combine them with high heels to add to the effect.
