I've been using Amazon for awhile now, BUT this is my FIRST review. These pants are interesting for a number of reasons...read on below.1. As many other reviewers have said, they have a very distinct odor right upon opening the package. The smell reminds me of burning plastic or some other type of chemical. This is the main reason I gave the product 4 stars instead of 5.2. You can take a look at my pictures. They fit very tight. VERY. I ordered a 2x to make sure they got over my butt and hips. They do, however they are still very snug. As you can see in my pictures, I wore them under another pair of pants for the reason in #3.3. I feel like I'm constantly looking over my shoulder to see who is following me, no lie. They are noisy!!! I would not ever wear these out to run errands or etc...they make a constant swishing and scraping sound so be aware of that.4. The product does do what it says nonetheless...you WILL SWEAT. If you notice in my pictures, I am wearing it with the zip up vest as well. I use these both when I work out.5. I would recommend them, just understand that you'll need to order a SIZE or two UP from your regular size, especially if you are curvy in the thigh and hip area. They should fit tight and not loose so I'm pleased with the fit.
