I'm almost too embarassed to post this. I felt so naked when wearing this, I cannot imagine wearing this to the gym to work out nor could I picture myself running errands and doing anything in the general public in such attire. I believe you cannot wear underwear as my "seamless" undies were still visible. I think maybe you can wear it with a sweater over it for modesty but I still couldn't picture incorporating this into my daily life. Also, I just felt like a baby wrestler.
