  • Amazon makes it so easy

  • The Ultimate Seamless Shaper
Size: Medium Color: Very Black
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. ... show more

  • Good for one to two uses only!
Size: X-Large Color: Very Black
After only a few washes, the lining is coming apart. I purchased 3 pairs and all three are ruined. Not a well made product. I wanted to return the item but the only free choices are if I bring it to a store unboxed. Ummmm no thank you that’s so awkward!!

  • comfy but fray in crotch area
Size: 1X Color: Cafe Au Lait
I love sooo much about these! Incredibly comfortable and no lines. They are almost perfect, except for the fact that after a few months of use the gusset area is fraying and the fabric is coming apart. Still comfy, but at this rate they'll get ratty pretty quickly - and for the price seems like they should last longer than six months or so. Too bad - they are my favorite otherwise. ... show more

  • Love them!
Size: Small Color: Soft Nude
At first I thought they wouldn’t be comfortable because they gave me the impression of leaning towards shapewear, but I was pleasantly surprised. They’re so comfortable you can wear them everyday. Very high quality.

  • It’s a trap!
Size: X-Large Color: Soft Nude
I have been looking for a supportive panel for some time and was recommended to try these, so in my excitement I bought 2 pairs. What torture! I suggest sizing down at least one size otherwise the back area stretches out within minutes and due to a lack of any real elastic around the legs causes loose hanging fabric which will instantly plant itself directly in your crack where it will happily stay forever, no matter how many times you try to remove it. Most expensive wedgie I ever bought and honestly it was impressive how determined it was. On a side note, not being deterred by my first bad decision, I thought I would try a smaller size thinking if the stretch were due to being overfilled with cheeks rather than just weak elastic, maybe they would stay in place .. sizing down did help with the wedgie issue, however that doesn’t help me with the $50 wasted on buying 2 pairs I refuse to wear. ... show more
