I recently wore this compression garment on an overseas flight, and it really helped minimize back stress during the eight hour flight.

It is about as hard to get on as you would expect from a garment that's basically a girdle. But if you get the right fit, it's comfortable when you do get it on. I have a 33" waist, so I got the small, and I use it on the outer row of hooks. I think it would be fine on the inner row for a 32" waist. 34" might fit if you don't mind it tight, but you should also consider the next size up.

This garment doesn't do miracles, but it does offer good support for the lower back, and would also work to shape you up for a public appearance.

By the way, the picture has it positioned too high. You'll almost certainly want to get it so the bottom edge sits just below the indentation at the base of your spine. That offers the best support and shaping for me.
