I think wearing a bra can get old after  while!  It is pretty warm here where I live, and a bra is another piece of clothing that traps heat close to the body.  I try to find every excuse not to wear a bra, as long as I can keep a certain amount of modesty, I do not wear such a contraption anymore.  I need to wear one under sheer tops, but the thing comes off, as soon as I am back home.  My girls enjoy the feeling to be liberated again!
But i still can remember the excitement I felt wearing a bra for the first time!
