The 11 Best Shapewear Pieces to Shop, According to Thousands of Customer Reviews What Is Spanx? Spanx is a brand of shapewear. The brand's first product was a footless, body-shaping pantyhose. The company has expanded its offerings from smoothing pantyhose to bodysuits and waist-cinchers, activewear, undergarments, leggings, and everything in between. Who Invented Spanx? Sara Blakely invented the first Spanx product one fateful night in 1998 when she was trying to find the right pair of undergarments that would make her look smooth under a pair of white pants. When nothing worked, she took a pair of scissors and cut the feet off her control-top pantyhose. Thus, Spanx was born. Do Spanx Hide Cellulite? The purpose of Spanx is to smooth out any bumps, ensuring your clothes fit just right and creating a flawless finish. That being said, there are three levels of compression to choose from based on your needs. Level 1 is smoothing; these are foundational, base-layer pieces that act as a second skin to smooth out any imperfections. Level 2 is shaping; these pieces offer extra compression and are a little extra firming than your standard shapewear. Level 3 is sculpting; for a total transformation, this level of maximum compression provides lifting and optimal slimming. How Do I Find My Spanx Size? Finding your perfect fit is directly related to measurements (waist, hip, bust, etc.), so your best bet is going with sizes you normally take in clothing — not going smaller, which will likely create discomfort. For leggings and tights, you'll also want to take your height into account. Once you know your exact measurements, you can quickly compare them to a chart on the Spanx site to determine which size is best. Do Spanx Come In Plus Sizes? Yes.

If wearing a smoothing undergarment makes you feel amazing and confident, great! If not, also great! Do you. Should You Wear Underwear Underneath Your Spanx? Spanx has a whole line of panties, and in that case, it is underwear. However, if you're debating on whether on not to wear something underneath Spanx's Shaper Shorts we say skip it.

When in doubt, take look at the instructions on the label to ensure you're properly caring for that specific item.
