I've worn foundation garments since high school. Once you get used to it, it just seems normal to wear them every day. I feel kind of naked without them. I even wear something under my workout gear... I just like to be "held" in at all times. I really like the high waisted Spanx Assets products sold at Target.
My mother was one of those 1950's brides who always wore a girdle, so I grew up watching her. She mentioned when I was a teen that wearing one might help prevent my stomach from sagging (I was already obese). So, I've worn them since then. I do think it has helped over the years. And, I'm hoping that when I'm at my goal weight I'll reap the benefits of all the years of use.
Losing again since January 2012
