Help a. Lot
This waist trimmer is very well-made and comfortable to wear during workouts. The material feels durable and supportive without being too stiff, and the adjustable straps make it easy to get a snug fit. It stays in place even during intense exercise and helps increase sweat around the midsection, which is great for cardio or strength training sessions. The added back support is a big plus—it provides stability and helps maintain good posture while lifting or doing core exercises. It doesn’t roll down or dig into the skin, which is something I’ve experienced with other belts. For the price, the quality is excellent. If you’re looking for a waist trimmer that boosts sweat, offers real support, and fits comfortably, this one is a solid choice.

Mermaid's Mystery Waist Trimmer Helps Give Amazing Slimming and Posture
Mermaid's Mystery Waist Trimmer size Medium I recently purchased the Mermaid's Mystery Waist Trimmer, and I must say, it has exceeded my expectations in every way! After trying out a cheaper alternative that didn't deliver, I decided to invest a bit more for better quality, and I’m thrilled that I did. One of the first things I noticed is the material. The neoprene is fantastic—it not only snatches my waist but also promotes sweating more effectively than other materials I've tried. As someone who has struggled to break a sweat during workouts, this waist trimmer has been a game-changer. The extra sweat helps remove toxins from my body, and I feel so much better after each session. Additionally, I’ve always had troubles with my posture, but I’ve noticed a significant improvement since wearing this waist trainer. After taking it off, I feel my posture has been corrected, and my waist looks slimmer too! The design with the Mermaid Mystery wording on the back is a clever touch; it helps me easily identify the center of the waist trimmer, making it a breeze to put on and line the wording with middle part of my back. I've found this product to be great not just for workouts but also for daily wear—even while eating! It has a way of gently reminding me to maintain proper form, and I notice I get fuller faster when it's on. The extra straps on the Waist Trimmer help to achieve that coveted hourglass shape, which is a fantastic bonus. Another aspect I appreciate is how easy it is to maintain. I prefer handwashing it, and the attached fabric loops make it simple to hang dry after washing. Just a tip—make sure to wash it after each use to avoid any breakouts from dirt or toxins. If you’re considering wearing it for extended periods, I recommend adjusting the tightness to ensure comfort, especially during long hours. While the sturdy Velcro does provide a secure fit, it can scratch your skin if left too close, especially when you're moving around. Overall, I would highly recommend the Mermaid's Mystery Waist Trimmer to anyone looking to slim down, improve posture, or enhance their sweat game during workouts. This product really targets those pesky belly fats, and the comfort along with the results is definitely worth the investment. I loved it so much that I bought a second one to alternate between washes! In summary, if you're in the market for a waist trainer that delivers quality, effectiveness, and comfort, look no further than the Mermaid's Mystery Waist Trimmer! It’s a fantastic addition to any fitness regimen or daily routine.

Worth it! Stop searching! Dont miss out!
*self edited for spelling errors...new phone in the middle of the night with Lil#3 up sick was probably not the smartest time..but really is the only time and I promised to get this info out!* Best Wishes! This product is actually really great. I didnt get it for free not am I being paid or compensated in any way to write this. I actually suffer from many autoimmune diseases/issues and their symptoms. In the not too distant past the doctors put me on a steroid that I had been on long ago but this time I had some kind of allergic reaction on top of steadily gaining @ 30lbs following the 10day (cut short due to reaction) treatment..and I also broke out in a bad case of shingles. Long story short: i was a mess..and a suddenly overweight mess at that. Among other contributing factors from all this, I think the additional weight on my small frame caused an increase in the severity of my chronic pain. I previously had one of those "as seen on tv" neoprene tummy wraps which did cause a lot of sweating underneath it but with the added support for my back. But "one size fits all" really didn't compliment my smaller build and i had to make adjustmente with velcro just to make it fit snug enough to feel good. THIS product however has size options. And while according to my new, and rather disproportionate measurments, the size chart wasn't all too helpful for me but I knew my build well enough to order a small regardless. And the fit is GREAT. The main wider piece wraps around and sticks with a full width of velcro so I can make it more snug when I want or more loose when I need. But then these added stretchy belts on either side that pull out and stick to the front for additional snugness and support are just amazing! It's not some weird length or shape; it fits from just under my bust to right on or above my hips (which is fantastic for another "problem area" of mine similar to "love handles"). I would recommend this to at least two groups of people: those trying to slim down/firm up their midsection (the sweating under the wrap is a GOOD thing!), and anyone suffering any kind of chronic pain issues. This has truly been a Godsend. I haven't gotten to wear it as much as I want to...but I most definitely will be. It seems well constructed and durable without sacrificing comfort. I use a blend of essential oils in a Jojoba base on my skin underneath it for some added benefits. But all in all, the product itself is totally worth it. And the price for what you're getting--you can't beat it. I could go on but I'll spare you ..if you came looking for something like this or are at all, even in the slightest bit interested...give it a try. I highly doubt you will be disappointed (other than the disappointment in yourself for not finding it sooner!) I will come back and post "before and after" pics after a couple months and before that hopefully a review & "how to" type video on what/how I do.. Because the product is just that great. -33yr old female, 5'5" and suddenly 150lbs from a usual 120lb-130lb range

Not made for curvy lady
It is a great item. But doesn't work on curvy ladies. The bottom lifts up when you start to move around

Nothing but good things to say - Just buy it!
This waist trainer is awesome. It is long enough to cover my entire fupa. Before buying, I thought the design was overkill but the extra straps in the front give the waist trainer extra reinforcement - it makes all the difference. I also like that it has bones but it's also comfortable enough that it works without making you feel restricted. The best part - this holds me so well and slims me down. I use it to gym but after compliments of people not knowing that I'm wearing it under my shirt, I will purchase another one as shapewear. It's also held up well from cleaning so far. Whenever I decide to wash a batch of clothes in washing machine, I unroll the waist trainer and add it to soak in the detergent for 20 minutes while the machine is OFF. I do this so I won't have to worry about getting a large container or filling the sink, but you can opt for that option if it suits you better. You can also use dishwashing liquid if you prefer and I'd also recommend adding a teaspoon of bleach just to kill any bacteria if you work out in your trainer. Then, I take rag with soap and rub both sides. After, I rinse it in cool water, just letting the water run on it and gently squeezing the material without trying to wring it. Then, I lay it open to air dry for the rest of the night. I try to wash mine once a week. After exercising, I also always leave my waist trainer laid out (foam facing upwards) so that the trainer can air dryer completely to avoid any potential smells or excess bacteria. Hope this helps!

Almost perfect..ugh.
Just used it for 3 sessions. It is comfortable and not crushing my stomach. The only problem is that there's a 1 and an half gap between the belt and the under area of my boobs. The suction of the belt is comfy and snug that it creates a little muffin top in that area. I ordered this belt cause it advertises that it covers all the abdominal area. When I put it on it barely covers the bottom of my stomach and it reaches below my under boob area. I did my measurements right and followed the size guide aswell read all reviews. I'm worried that it might create an uneven or weird shaping due to how the belt doesn't cover ALL of my abdominal area. I don't even know if I should return it or look for another one because this one feels good while exercising but that gap- that gap is causing me some unnecessary sensory discomfort.

Great waist trainer! Just as good (if not better) than Sweet Sweat!
For five years I've worn waist trainers for every work out. I've always gotten the Sweet Sweat brand and have really enjoyed them. They can last almost two years and get the job done. My only complaint with the Sweet Sweat was that it wasn't long enough to cover my entire torso and that they are a little pricey. However, I always repurchased because I'm a creature of habit and they absolutely gave me back my shape after I went through a massive weight loss. I was about to order my fourth one and decided to take the plunge and try something different (and cheaper). After a good bit of research, I decided on this one and I don't regret it! It covers more of my torso and is comfortable no matter what workout I'm doing (strength, hit, cardio, yoga, etc.). I was a little concerned that the boning in the back would limit my mobility, but it's pretty flexible and I've noticed no significant difference from the Sweet Sweat. It also makes me sweat just as much! It is a little thinner than the Sweet Sweat, but I actually prefer that, and it's just as durable (I've had mine now for about 3 months and I workout approx. 5 days/week). I ordered the medium based on the measurements -but I could've ordered the large too (the sinching straps on the outside have no overlap, but the Velcro is strong and they always stay in place, so it's not a big deal). If you're a user of the Sweet Sweat and are debating whether to make the change - do it. This product is performs just as well, is half the price, is just as durable, covers more surface area, forms your waist, and makes you sweat!

Perfect Waist Trainer for Long Torsos and Weight Transitions
I’ve had this waist trainer for a long time, and it has been a constant companion throughout my weight loss journey. As someone with a long torso, finding a trainer that fits well and stays in place has always been a challenge, but this one checks all the boxes. I originally bought it when I was 230 lbs, and it still fits perfectly now at 195 lbs, thanks to its adjustable design. The coverage and support are excellent, and it really helps to target and increase sweat during workouts, making me feel like I’m getting more out of my sessions. Durability is another huge plus—I’ve used it consistently, and it’s still in great shape. It’s been there for every stage of my fitness journey, and I can honestly say it’s one of the best investments I’ve made for staying motivated and feeling confident. Highly recommend!
