SPANXshape Invisible High-Waisted Thong

I have been wearing shape wear routinely since my son was born over a decade ago. I wear some sort of shaper almost every day as I find mild compression on my stomach to actually be comfortable and like that it helps me maintain a healthier posture since I’m getting old enough to start caring about such things! I will admit that over the past few years I’ve deviated from Spanx brand, and while I’ve found a few from other brands that were quite good, there were many that were awful, and not ONE non-Spanx shaper had this high quality for anywhere near the current $48 asking price. I truly can’t get over how wonderful this shaper is and that it’s not well over $100 — I see now that you really can’t do better than Spanx! This is what I’d consider a medium intensity shaper: it holds you in and makes you appear a bit slimmer and certainly completely smoothed out in the waist area, but it’s not corset-level nor is it light coverage. I ordered size Large and I’m 5’7” and around 167 lbs and my waist/mom pooch is definitely my “problem area”! Once I had this thing on correctly I was amazed at how it fit like the most natural second skin: this Spanx shaper is thin in a very good way. It’s my perfect coverage level: enough that my waist is held in, but not at all binding or uncomfortable. Helpful hint: if it’s bunching up at all at the crotch, you probably don’t have it pulled up all the way! When it’s on correctly the top should lay directly below your bra/bust. For me it fits perfectly, no issues at all with bunching of fabric or the ends coming up or down like other shapers will often do. If you’re having any of these issues, make sure it’s all the way on, if it is, you may need a different size. I am usually a size L in pants and I always order my shape wear in size L as well and it can be a tight fit at first while pulling them on but it’s usually the right size for me. If you’re stuck between two sizes, I’d recommend trying the larger first so long as you’re able to exchange it if needed. I hope this review is helpful! :)

I wore this high-waisted thong for a full day under a form-fitting dress, and honestly—I was impressed. From the moment I pulled it on, I could feel that it wasn’t just underwear; it’s definitely shapewear. The fabric is super smooth, but not rigid or scratchy, which makes it really wearable even for long hours. The “waist snatch” effect is real: it gently compresses around the stomach and midsection without feeling like a torture device. I noticed a slimming effect, especially when I sat down — it helped smooth out my profile in a way that felt natural, not overly cinched. One of my favorite features is the silicone-lined waistband. That grip worked: the thong stayed in place all day and didn’t roll down, which is a big deal in shapewear. I didn’t have to constantly hike it up or adjust. On the downside: the thong part feels a little more noticeable than lighter thongs. After several hours, it can start to feel a bit “present” behind, especially when sitting. Also, getting it on isn’t totally effortless — you have to stretch it a good bit to pull it up over your hips. In terms of comfort vs. shaping, it hits a really smart middle ground: subtle shaping (not like super firm spanx), but enough to make a difference under tighter clothes. For someone who wants to smooth without extreme compression, this is a very good pick. Would I buy it again? Yes — especially for dresses, workwear, or any outfit where I want smooth lines but don’t need hardcore shapewear.

This is an easy 5 stars for me. I ordered a size Large and I’m a women’s US 10/12, and the fit is perfect. It snatches my waist and flattens my stomach without feeling uncomfortable or overly tight. You definitely feel supported, but not squeezed. I wore this to my bridal dress try-on and it was flawless. No lines at all, everything looked smooth and seamless under fitted gowns. The high waist stayed exactly where it should, and the grippy waistband really works without rolling or slipping, even after moving around a lot. What really stands out is the value for money. For the quality, comfort, and results, this is honestly the best you can get. I’ve tried other shapewear, and nothing compares at this price point. SPANX absolutely delivers here.

I’ve worn the SPANXshape Invisible High-Waisted Thong multiple times now under fitted dresses and tailored pants, and it delivers exactly what it promises—subtle shaping without visible lines. The fabric is lightweight, smooth, and breathable, with just the right amount of compression through the midsection. It smooths the waist and lower abdomen without feeling restrictive or uncomfortable, even after several hours of wear. The high-waisted design stays in place and doesn’t roll down, which is something I always watch for with shapewear. As a thong, it does a great job remaining truly invisible under clothing. There are no seams or edges that show through, even under thinner fabrics. Comfort-wise, it’s surprisingly easy to forget you’re wearing shapewear at all, which speaks to how well it’s designed. This isn’t heavy-duty compression meant to dramatically reshape, but for everyday smoothing and confidence under clothes, it works extremely well. The quality feels consistent with the SPANX brand, and after several wears and washes, it has held its shape and elasticity. If you’re looking for reliable, discreet shapewear that enhances your silhouette without sacrificing comfort, this is an excellent option.

So these are a STRUGGLE to put on. When I opened the package, it looked child sized. Attempting to pull this up my body felt like a Herculean effort and immediately upon accomplishing the feat, I promptly took them off. The compression is out of this world and the shaper goes all the way up under the bust. It felt not uncomfortable but…weird. A large part of that I’m sure is because I don’t typically wear shape-wear but I think part of it too is just the extreme compression. If you are looking to feel like a stuffed sausage in the best way possible, buy this panty.

Definitely holds everything in place. I’m not sure I’m going to be able to last the night in it though. Definitely going to have to wear it around the house and get used to a full coverage one. But their fabric is nice and doesn’t feel bad I’m just going to need to get use to the squeeze in places I don’t typically wear compression. It does definitely slim down my mommy areas though. So I think it’ll be a hit on date night.

I ordered this invisible waisted thong to wear under a form fitting dress. This was for a special occasion so I wanted to look my best. When I received this item I looked at it and thought “no way will this fit”. Fortunately this has a decent amount of stretch and the fit is surprisingly good. I’m not a fan of thongs but found this one comfortable for an evening out. As a woman ‘of a certain age’ I needed help with a little ‘smoothing’ and this did the job.

This high-waisted thong does a great job of smoothing without adding bulk. The fabric is thin, lightweight, and very soft, and it lays flat under clothing without creating lines. The high waistband offers light shaping and stays invisible under fitted dresses or pants. I found the compression to be moderate—enough to smooth but not restrictive. Sizing seems accurate, though those between sizes may prefer to size up for more comfort at the waistband. Because it’s a thong style, it eliminates visible panty lines entirely. Pros: Very thin, lightweight fabric Completely invisible under clothing High waistband provides light smoothing Soft and comfortable material No panty lines Cons: Waistband may roll slightly depending on body type Shaping is light, not firm Bottom line: A comfortable, invisible high-waisted thong that gives a smooth look under clothing without heavy compression. Great for everyday wear or layered under more fitted outfits.
