and don't really need the support of a bra?
I've started doing it recently..not under very sheer clothes but under a lightweight jumper and today with a wrap dress.
The reaction has been unexpected! Two friends who said it was overly provocative and another who said "what will you do in the chiller bit in tesco" 
Male friend who commented on my lack of bra and said its much more out there than having big boobs on show.
Thoughts?
