Comfortable! Tight! Works just as described!
Tight! But that’s what I was expecting! I read a lot of the reviews saying they had to order one right after the other which is what I wanted to avoid. It took some wiggling to get clasped but that’s because it’s a bit smaller than I should’ve ordered. I believe I ordered a medium. Which i had a feeling was a *little bit* too small. I was right, but I bought it in the smaller size for a reason! It’s super comfortable to wear, I can bend and twist and nothing comes undone or loosens. The fabric is soft for a waist trainer, not boney. Which most are. I bought this to help with losing about 20 pounds along with a weighted hula hoop gadget. I’ll update more once something has changed! I’m writing this review December 15th 2025. I’ll update again in a few months.

Awesome!
I absolutely love this waist trainer. From the very first use, I noticed how much it helps me sweat in my abdominal area. The material is comfortable, doesn’t pinch, and fits the body perfectly. It stays in place during workouts and even helps with posture. After using it during my routines, my stomach feels warmer, and I can definitely see better results in my workouts. The quality is great, and it arrived quickly. I highly recommend it if you want to sweat more and boost your fitness results!

Almost didn't fit but did. Female, Weight gain & larger breasts
UPDATED PHOTOS! JAN 6, 2026 (I got SMALLER) I WENT FROM AN XL TO L TO M TO S AND NOW ABOUT go down to a size XS!!! YALL IT WORKS. Started weight 206. Current weight 151.5 lbs. For anyone looking at the XL & XXL sizes for this waist trainer & aren't sure if the XL will fit you (i would size up to the XXL) (Plus you have 3 rows on that to tighten) Hello I'm 28 Female. 5FT5. Almost 5FT6 & currently on a weight loss journey again for the humpteenth time. Anyways. I have gained weight, & around 35 - 50+ lbs that I'm currently trying to lose. Current weight is 196-198 lbs fluctuating. My normal weight is about 139-155 lbs..... but since my current weight is 196 lbs i ordered the XL since i wear XL in clothes but probably should have gotten an XXL. (I had to lose a little bit of weight before i was able to wear this. So it sat in my closet for about a month. Upon unhooking it to open it up and puting it around my waist I got alittle nervous as it seemed to be an inch or more too small & i thought oh no maybe I should have ordered a XXL instead of an XL. I remembered when I had waist trainers years ago that they were a bit difficult to get on at first. I tried my first attempt standing up, i put it around me standing up with extremely straight posture while sucking in my belly alittle bit as I got the first hook on starting from the bottom once I got the first few hooks hooked it got alot easier. I slid down the waist trainer every little bit the further hooks I got done.. finally got it on. Now it's tight but comfortable tight, remeber I'm a beginner I haven't waist trained in years and have gained weight so it's going to take wearing it for a few days to a week to get used to it. I normally wear a tank top under my trainers. I wear this one on bare skin. Its the most comfortable feeling waist trainer I ever had on, it feels thin but is hugging me all around where it's supposed too, it definitely made my waist look smaller, the material is more stretchy in my belly area when I breathe in. Ive purchased out other waist trainer brands from Amazon that were stiff, the wires in them (the bones) hurt my sides and it rolled at the bottom when bending & also the material didn't expand out with my stomach making breathing difficult. As for the last part of getting this waist trainer onto your body..... its the zipper part after you get the hooks on (I'm on the 3rd loosest row of hooks "of course" (i honestly thought i was going to have to walk around with this waist trainer unzipped. It was too small. I needed an inch more to be able to zip up. I had to lay down flat. It took me seveal tries... I almost gave up but once I started the zipper at the bottom & then used both hands to pull the 2 parts of the material closer together to help the zipper go up that helped me tremendously. I've noticed you have to get it on and break it in alittle bit, getting it to fit your body. Give it time it will! Con: Hurts my boobs a bit when sitting (for bigger chested girlies). If you have larger breasts this could be a con but I deal with it. 🤣 I will have to come back & update with pictures of my results of my weight loss journey & waist training journey. I'm going to come back in 1 month.

Size up
I am a size medium, and this waist trainer is really good quality, but it runs too small so I had to size up.

Great fit
wasn’t expecting much, but this waist trainer surprised me in the best way. The material feels sturdy without being stiff, and once it’s on, it stays put even during cardio. It gives that snatched look instantly, but what I like most is how it warms up your midsection so you actually sweat. After a week of wearing it during workouts, my lower belly already looks a little flatter. It’s comfortable enough to wear for a couple hours without feeling like you can’t breathe. Definitely worth it if you want something that shapes AND helps you sweat more

Great product for the price
I bought a size medium. My range of weight is around164-180 (when I’m festive happy) I’m 5’3” .im curvy, have a slim waist. I purchased the medium since it’s the same size as my other waist trainers which I love but I wanted something a little longer and I love the this one is to cover my fupa , that little flab of pregnancy skin. I use this to workout in and made me sweat good!!!! I would say this is true to size, I’m actually on the last row of hooks without issue, it was a bit hard to zip up I had to lay down for that but it went right up and it didn’t zip down or anything. It doesn’t roll up or down and stay put. The quality is great. No funny smell either. Honest & accurate review. I did NOT receive this free I just want to help other gym enthusiasts and REAL women with REAL bodies!

Great until it wasn’t
Worked great and fit wonderfully until I bent over one day and felt something sting my back . One of the bands snapped on me and left a welt on my back from where it got me . I loved it otherwise that just hurt a good bit. The hold was great keeping everything held in . The zipper and everything held together . Helped sweat a lot which was great because half the time I didn’t even realize I was sweating until I took it off . I loved the style and how it pulled everything in . It didn’t look terrible under shirts either . Tighter shirts you could definitely tell your wearing it but it wasn’t super uncomfortable. So it wasn’t bulky just have to wear a tad looser clothing if your worried about somebody seeing you wear it .

Works for me.
It definitely runs a bit small, but I was able to squeeze into it with a bit of effort. Overall I like the fit and it’s good quality for the price.

It is ok so far, but I would not buy it again. The elastic is getting loose after 2 months.
