I think if you are worried about how you look wearing something in public then you should not wear it in public, Period. But public includes the time riding your bike. Don't pretend people don't see you all hunched over perched up on that saddle. The schizoid quick change stuff just speaks to low self esteem / insecurity which is really what is unattractive. Be an adult and own your choices.

When you worry about how you look you should consider who it is you are trying to impress. Is it the lazy uninspired sarcastic slacker or the active, engaged, out going confident life lover? I don't waste time on the first and the second category get what cycling clothes are about. They also probably wear tennis shorts, jogging shoes, golf shirts or yoga pants.

There's nothing in cycling that precludes one must wear bibs that reveal ones junk or shirts that accentuate every curve. Lot's of choices out there.
