I'm a size 4 or 6 and wear the Spanx Higher Power thing that the PP linked to every day under my work clothes. I don't find it uncomfortable (because I bought the correct size and didn't try to squeeze into a smaller one). I love that I never have panty lines and am always smoothed out. I change out of my work clothes as soon as I get home (and don't wear Spanx on the weekends unless I'm going to a fancy party or dinner), so my husband never sees me in my girdle.
