My work yearly party was last night (it is like our Christmas party but we hold it in January). There is a buffet, some mediocre wine, a too long program and then then just visiting and dancing.
I wore a size 16 LBD that looked GOOD -- not tight.
I wore 4 inch heels (not my usual) but was able to make it through the 4 hours. I was even dancing a lot. At one point, 2 of my coworkers (who are zumba teachers) started a routine they knew and I jumped in. It's harder in heels! Then "Gangnem style" came on. I hate the song but my zumba teacher has a routine and I remembered most of it. Everyone was following ME. They even asked how I knew the routine.
And, having been a zumba girl for the last 6 months or so, I knew lots of moves and was really dancing "as if no one can see you, " thrusting my hips and shimmying with abandon, not worrying about how I might look. I felt pretty comfortable in my own skin.
And that, my friends, is a BIG NSV.
