Size down for my support. But really like the them. They do what they are suppose to.liked the soft, thin, fabric that still works tucking your tummyThese are a super soft fabric and provide a decent amount of hold without causing extra bumps. They’re very comfortable - but I think the fabric that goes from the crotch and up the back could be a little slimmer and it gets a little uncomfortable every so often and requires a little readjusting.These are pretty comfy and have a surprising amount of coverage for a thong. They're high-waisted but never rolled or bunched like a lot of pairs do on me.There isn't much compression, just a little bit of smoothing. I wonder if they'd do more if I went down a size, but I'm happy with them being comfortable instead. I think you'll still notice a bit of difference in tighter clothes.I have always heard of the wonders of Spanx products so I thought I would give these thong underpants a try. They are very soft and do have some tummy control. Keep in mind, they do have cotton content and do shrink some. I do still get lines due to the thickness of the edge hemming. Also, for me the thong is a little too wide, so it gets a little uncomfortable. I probably will not order more considering the price of a single pair undies.This is my first time trying Spanx Cotton Comfort, and the name doesn't lie. This is an exceptionally comfortable thong. The material is thin and buttery soft. The seams are so smooth that they feel pretty much seamless. They stretch nicely, and the stitching is very nicely done.The fit is perfect for me. I used the size guide in the listing photo, and it was accurate for me. When buying the brand's faux leggings, I sized up to medium, but I always wear a small in the shape wear. I am on the lower end of the size range though, if you are closer to the end of the range, you might want to size up. They should fit comfortably to smooth. Too tight and they bunch up.These are high waist underwear, and they hit right at my belly button. The back fits just right and stays in place without issue. They feel like they fit and support naturally, but they do not have much in the way of compression.Bottom Line (no pun intended): This is a high quality product that is worth the splurge if you are looking for a comfortable thong. But, if you are looking for more shaping and sculpting, these might not be your best bet.I love these underware from Spanx! I typically do not love cotton underware, but these are the expection. They hold up to spanx standards or quality and what I expect from them. I purchased a Medium and am 5'4'', 155 lbs. They fit me perfectly!Pros:1. Material (55% Cotton, 25% Modal, 20% Elastane). It is a nice soft cotton, not hard or scratchy.2. Cotton gusset.3. Shapeware underware with high waste to hold you in and make you feel secure.- Love these with high rise leggings!4. No Roll wasteband5. Smoothed out all my rollsCons:1. Not seamless so you can slightly see seams under thin leggings, but not as bad as most underware.Will definately be purchasing another pair, these boost my confidence and make me feel so good!This thong offers very light compression across the belly and lower back (the love-handles area) and stays in place without rolling. The material is a soft and smooth cotton blend.It is noticably less supportive than other shapewear I've worn, but is really easy to get on and incredibly comfortable. I usually think of shapewear as something to put on under "special-occasion dresses", but this is something I would order again in other colors and could become a daily go-to. Definitely recommend.
