This waist Cincher is the truth!! It's the second one I have purchased. My first purchase was a 5XL when I was a size 18W, in the past 8 months, I have lost weight doing a ketogenic lifestyle and I'm in a size 12/14 so I had to get a new one. My second purchase was a 2XL and it fits great. I love this thing. It holds in my tummy and gives me a great shape. I usually wear this with my dresses for church or date night with my husband of 20 years. I don't get hot wearing this, however I'm usually in air conditioned environments. If you sweat a lot, you will have a moist tummy when you take it off. I would definitely recommend it.
