Slimpressions is available in five sizes: 1, 1 Petite, 2, 2 Petite, and 3. Sizing is flexible, similar to that of pantyhose, and is based on your pant size. Size 1 fits womens pant sizes 2-10. Size 2 fits womens pant sizes 8-16. Size 3 fits womens pant sizes 14-22. Petite Slimpressions have shorter torso and arm lengths to accommodate women who typically wear petite clothing. For a tighter fit in the mid-range, choose a size down. Alternatively, for a looser fit in the mid-range, choose a size up.
