My saddlebags are why Spanx exist! Now that I have a baby I also have a muffin top.
I cut the feet off of a pair of panty hose and it allowed me to wear a pair of great strappy sandals. I didn't see lines but the hose rolled up at my feet - and that's how Spanx born.
In the next decade, I see Spanx going worldwide. Everywhere. No butt left behind. It's going to be all over the world and it's going to be an aspirational brand that transcends categories. There's so many things we can improve upon and make better.
