Size Guide

Take your measurements


To find your correct size, use a tape measure and take these measurements. Stand with your back straight in front of a mirror, to make sure that you measure correctly and that the tape measure is kept level.


Measure under your armpits, around your shoulder blades, and over the fullest part of your bust. Don’t pull the tape measure too hard. For fitting a bra, you also need the measurement just under your bust.


Measure around your natural waistline. This is the narrow part of your waist, about an inch above your navel. Relax and breath out before you measure.

3. HIP

The hip should be measured around its fullest part (about 8 inch. below your waist).


This is the measurement from your ankle to your groin, when you stand with your legs straight. If possible, ask a friend to help you. This can also be measured on a pair of pants with the proper length.

Snug but comfortable

When I first tried it on I thought it would be too small. But once I got it on it was very snug and I feel like this will be a good waist trainer that has great quality For 2021.

very cute products. I enjoy the fact that it doesn't make any noise when I'm walking like other waste trainers do, very supportive as well.

Great waste trainer

Been using it for about 3-4 days regularly in the mornings. It fits great, I am a size large in clothes but purchased a medium so it could be nice and tight. I do wear my high waisted leggings under it because it does mark my skin, a little uncomfortable at first but then I did get used to it. Wraps around my body just right and I love that strap to make it tighter as I lose weight and it does make your tummy area sweat/get warm while it's on. Definitely recommend and look forward to purchase a size smaller once I need it.

Love it! Comfortable and feels right.

Having a flat as a board midsection is one of the things I most miss about the way my body was in my youth. As a teenager, my secret to that flat middle was swinging on the swing set at the park for 4 hours every day (I do also have a long torso which is genetically lucky and long torsos tend to have flatter middles).
After my firstborn I was fortunate, and also young enough, that everything went back to normal. But I had twins a couple years ago and now it's all loose and soft. In my 30s now, it just seems to be getting worse. I've got a pouch of flab I just can't get rid of no matter how many "Flat midsection" exercises I do. So I'm hoping this helps.
I had a different waist trainer from a big box store that was a cheap five dollar one-size-fits-all Velcro and it just kept coming loose and sliding down to my hips no matter how tight I put it. This one is SO much better! With clasps and zippers in addition to the Velcro, it stays in place. Having a waist that is exactly 30 inches I was debating to get a medium or a large. I went with the medium and was surprised at how well it fits. Like a glove! And the metal clasps are all the way at their tightest and it's still comfortable. I'm typing this right now while wearing it. I'm excited to see the results. Well worth the buy!

This waist trainer is awesome!

I was super skeptical about buying a waist trainer and I have debated it for years. I finally purchased this one and I am so happy I did. The quality is great. I love that it has the hooks, zipper, and velcro to really keep everything tight. It is very comfortable to wear and the boning in it does help me to not slouch. I have the ever frustrating love handles and tummy pooch and this sucks everything in. It makes my belly sweat not profusely but in small amounts so hopefully some of that tummy fat will go away. It does not make my skin itchy. The material is stretchy and soft. I am 100% happy I bought this. I am also 5'4" 130 pounds and I ordered a small and it fits perfect.
