I got this product 2 days ago and was able to wear it all day one the first day. It's very comfortable. I got a medium because I'm typically a medium/large in women's clothing and a medium in men's shirts. I'm 5'3" and about 145-150 pounds. I do have a short torso and was worried this corset would be too long but its absolutely perfect. I have terrible posture and arthritis in my spine so I decided to try a corset out. I've had various ones in the past that were ultimately just too uncomfortable to deal with. The quality of this item is great and structurally I've had no issues. In the past, I've had the boning in corsets pinch and bend into one side (us mom's know we have one love handle that's bigger than the other because of how you hold a kid on your hip).
