I agree with rtjdk2 about the skin having stretched a bit and it will get tighter over time, especially with exercise.

The other thing is that there will be a period of about 6 months when the fat will seem to redistribute and you may get closer to where you were and how looked on the way up. Again, exercise as Nat suggested will help.

I am envious that you had so little to lose and probably (in MY eyes) your 'baggy thighs' are almost invisible. I tried to get my hip surgeon to do some liposuction while he was replacing the joint and he couldn't tell if I was serious or not. (I'm not sure either.) At least, having lost 40 pounds, there was lots of skin available for the post-op swelling without further stretching.
