Here's me as of today. I don't have any real "before pictures." My rule was "You can take my picture as long as I never see it." The dress try-on from March 2009 will have to do.
What I can say is that before IP the camisole didn't stay down over my tummy, I stopped wearing it when it started rolling up over my rolls. The pants are new, but 2 sizes smaller than I used to buy. But with women's sizes, who really knows. For sure they wouldn't have got much past my thighs 5 weeks ago.
I mentioned before that I'm losing weight in my arms and legs first, looking a little like a childs picture - round body with stick arms & legs.
Looking forward to my belly fat disappearing.

You look fabulous. My highest-ever weight was also around 260 and I must say- your stomach looks fabulous. I have a lot of stretch marks, but yours looks so smooth and, yes, svelte! And... I disagree, I do NOT see a muffin top in those pants. You look awesome and are an incredible inspiration. 
No kids = fewer stretch marks.
