Yes, I have.
I have the
Divine Collection Jolie Thigh Pads, which are self-adhering. Similar to Chrissy I was not happy with how square my body looks in the mirror and those hip pads make a huge difference, especially when wearing pants or pencil skirts.
While I would much prefer having my own curves and not having to deal with the pads, I do love them and wear them regularly and quite frequently.
While they are self-adhering I found that I have to wear pantyhose, leggings or some cyclist-style shapewear that covers my upper thighs to prevent them from falling off, especially in the summer months when some moisture might build up on the skin. Going to the restroom is not easy as they have a tendency to peel off when sitting down, especially in summer.
But I do love the curves they give me!
I also have a cheaper pull-on set of foam pads in a piece of shapewear, but I rarely use them as they are a bit too thick giving me an unnatural butt and they also move around a bit. Only advantage of that style is that they are easier to handle in the restroom.
