Large breasted women have my deepest sympathy - I know that big boobs are sexy, but they are also hot and sweaty and get in the way and bounce around when you don't want them to. So the wearing of a bra is a non-negotiable fact of their life. I however, am grateful for my less than ample assets - especially when it comes to the "joys" of bra wearing.
I can buy a bra to hoik (wiki definition: to lift something up wildly) me up and give me a little bit of cleavage when I go out and need to fill out my dress a little more. I can buy a bra to keep my attributes from showing through my shirts at work (very important in middle age!), and I can get a sports bra to save me swishing around wildly if I am silly enough to engage in anything remotely energetic (a very rare occurrence!) But ohhhhhh the bliss......of taking that bra off at the end of the day and pulling on a comfy shirt and just letting everything be free. I love that comfort and freedom of not being trussed up and under-wired and bra strapped, and I love that I don't need to put up with it all when I am in my own home.
I have also worked out that if I put a nice singlet top on under what I am wearing, no-one is any the wiser about whether I am bra-less or not (as long as I don't get really cold or jog on the spot - both would be a give away). Seeing I am not a jogger and I rarely get cold (living in Australia ensures pretty warm temperatures for most of the year) I am fairly safe in the bra-free department. That means I don't have to worry about an unexpected visitor catching me deshabille (great word hey?!).
So I will continue to maintain society's norms during the working and socialising parts of my day, but if you listen carefully you will probably hear my sigh of relief when I arrive home and remove that item of torture and go back to the state nature truly intended for me.
