When choosing skirts and pants, go for the ones that sit higher on your waist and hence bringing attention to your natural waistline. Always keep in mind the 1/3 to 2/3 rule. Your upper torso to the natural waist (that is the smallest part of your waist) being the 1/3 and below your natural waist to make up the remaining 2/3. This rule will ensure that your height is maximised.

To further define your waistline, tuck in that top! Defining where your waist ends and where your legs begin also does wonders to adding height!
