I bought them a bit bigger than my actual size based on other customer reviews and it came out perfect. I have a severe case of unflattering backside, and these are just the right thickness! Anything thicker and it would look fake! These are so comfortable, I literally don't even realize I'm wearing them, yet I feel my pants fitting me better, and I have a lot more confidence. I only wear them for key events, a few times a month, to not out-wear them.
