I purchased this product hoping to be able to wear it throughout a regular day under my normal clothes. This body slimmer is very difficult to get on. I was right in the middle of the medium size chart and I bought the medium. I wish I had gone a size up. If you measure anywhere from the middle, to higher size bracket on the size chart I would recommend getting the next size up. Once you get this shaper on, it really does do what it says! It instantly smooths and shapes. But, I found that as soon as I moved around, the top of the shaper would slide down my back slightly and the bottom of the shaper would slide up my back, therefore buckling in the middle of my back. I was constantly pulling up and down on it to get it to fit right. I could never wear this out because of this. This shaper is great if you are going to be standing in one place, not bending or sitting or moving. This product with shoulder straps to hold it up would be better and I didn't look on the website to see if that was offered. I recommend this product for around the house only.
I'm not sure how this tank qualifies to be a slimming tank. There is no elasticity to it at all. This tank is a really nice basic tank top, but not in any way a slimming tank. Do not buy this tank if you are looking for slimming qualities.
