Love my new define vest duo

I got it today and it was easy to put on and make me feel so good in it ! I look slimmer already just putting it on. It feels comfortable as well. I will come back in a few weeks to follow an update on it. But so far I’m in love. Hopefully I see results soon enough! Size 4x

The Real Deal

I Love my Waist trainer. It’s great to work out in and produces a lot of sweat, good sweat. It helps you feel like you are getting the most out of your works outs. It made with good material. It not going to rip or tear. It holds you securely. I recommend 10 to of 10!!! Oh and be sure to go by the sizing chart and size UP one or two sizes. I’m normally a size 3X & the Sizing chart provided sized me at 5-6X so I got my shapers in 8X and they fit as they should.

Excellent product

Very good. This item has physically changed the appearance of my body. I used it 6 days a week while i work out and around the house. I have had this product before over two years ago and it did the same thing. Very useful. Extremely comfortable when worn properly

Really enjoying it

Love the design with one suggestion…placing a hook at the top of the zipper. I’m in it really good and it takes some effort to get it zipped but it comes down sometimes. Other than that, I love it!
