I am with Thud. Also, nothing will fix the fact that you have not worn a bathing suit in years except TADA! putting on a bathing suit. I work at a pool and wear a bathing suit all. the. time. and I weigh much more than you. As adults, it's easy to get out of the habit of wearing something so revealing but I promise you no one is noticing. The only thing that happens when you don't wear a bathing suit is you don't get to have any fun. Just go have fun. If you are perimenopausal, you are too old to worry about anything but living your best life. Now. With the body you have. And getting in the water is one of the best ways to get in shape and help lose weight. Don't wait!
