Wow... a fabric type bra is old school. I don't think anyone on the board has one. A few of us (myself included) have some type of clear bra. Obviously a whole lot more than a fabric bra, but it doesn't show and you don't need to take it on/off based on weather.
I had one wayyy back and I only used it for long trips, had to take it off in the rain and then couldn't put it back on the car until it was cleaned.
