Review: Great infront, fails in back. - These do what they say, they smooth out ur lower stomach and stay up. The back is the problem. It continues to ride up so while u feel comfortable w ur front, ur constantly trying to shimmy the back down to hide panty lines. Its pretty irritating, but if u have a tight fitting dress, it does the job if u can handle the wiggling to readjust the backside!
Review: The Ultimate Seamless Shaper - As someone who frequently wears form-fitting clothing, finding the right undergarments that provide a smooth silhouette is always a priority. The SPANX Undie-tectable® Brief has quickly become my go-to choice, and I can't recommend it enough! From the moment I slipped these panties on, I was impressed by the level of tummy control they offer. The high-waisted design provides excellent core support, smoothing out any bumps or bulges, ensuring a flattering shape under even the most clingy fabrics. But what truly sets these briefs apart is their seamless construction. The rear area is completely smooth, eliminating any unsightly panty lines or indentations. This feature is an absolute game-changer for those of us who want to rock figure-hugging dresses or skirts with confidence. Despite their firm compression, the SPANX Undie-tectable® Brief remains surprisingly comfortable. The breathable fabric and well-designed waistband prevent any uncomfortable digging or pinching, allowing you to wear them all day without discomfort. In terms of fit, these panties run true to size, and the wide range of size options ensures that everyone can find their perfect match. I appreciate the attention to detail in the sizing, as it contributes to the overall streamlined look and feel. Whether you're dressing up for a special occasion or simply want to feel confident and supported in your everyday activities, the SPANX Undie-tectable® Brief is an investment worth making. They not only enhance your outward appearance but also provide the confidence boost that comes from feeling great in your own skin.

*by H***R on May 9, 2022*

I'm slender, 5'6 and 117 pounds, but I've had two kids so I don't have a flat stomach anymore and I have butt cellulite, the latter being what I bought these for. I didn't want the dimples in my behind showing through my satin skirt or a pair of trousers I have. I will say that once on, these made everything look smooth and what I was hoping for. But they don't stay in place AT ALL, and in fact, created rolls I don't have, like a big muffin top below my 28 inch waist. And hip dips. The worst part was the bulge they created on my right butt cheek when they rode up. I went to the bathroom to pull them back down but as soon as I sat down, there went that right side again. I felt so self conscious. I actually think my body would have looked better without the Spanx. A little cellulite is preferable over a muffin top and a right butt cheek with a big old crater that wasn't there before. Unfortunately I can't send these back because I wore them. You really cannot tell what a pair of Spanx is going to do until you walk around in them for a few hours unfortunately. I'm back to searching for something else I can wear under my clothes to smooth my butt and based on the reviews I'm seeing, I'm not finding anything that doesn't create rolls, show through clothes, or cause misery, etc.
