I wouldn't say that I have "anxiety" about wearing Spanx (and honestly, no one SHOULD have anxiety about wearing a brand of sucky-in-y underwear - because that's essentially all they are) but I HAVE noticed that when I'm wearing a tight dress, along with - what is essentially a modern day girdle - I feel, a little.... well, anxious. Stiff. Uncomfortable. There's a tightness in my chest.../abdomen.
I mean, most of that is the sucky-in-y part of the underwear that I paid $50 to literally wedge myself into so that I could look good in a dress for a few hours, but you know what I mean. I worry. The Spanx alter blood circulation to my brain (probably, I don't know. You'd think they've got to be cutting off some circulation around my torso. Otherwise, are they even doing their job?) My inner fat girl that needed the Spanx in the first place starts sending paranoid, worried signals to my brain.
"What if people can tell?" I think. "Can people tell that I'm wearing a girdle?"
I honestly do not know how anyone would ever be able to "tell", unless they came over and lifted up my dress and said, "Hey I see you're wearing some funny underwear under there." And if someone ever does that to you, I can PROMISE you that the the highlight of that story will not be "I was wearing Spanx", it will be "A stranger lifted up my dress. It was weird."
