As long as you're upfront (but no too upfront!) about it and you have accurate pictures, I'd imagine you'd still get bookings.
As others have said, quarter cup/balconette bras or corsets would allow the majority to be on show without exposing the scars. Once in a booking, punters who ask for you to take it off could be informed for the reasons and make a decision from there.
You'd be surprised the number of punters who, frankly, don't give a shit. I've seen plenty of surgery scars on boobs (granted, usually the result of augmentation) and it doesn't phase me in the slightest. The fact there are boobs is what counts!
As I said at the top, be honest. The last thing punters want is the scars, your attitude to them, or your idea of what their attitude is to them, affecting the service you provide. If you're honest and they book you can be happy they're happy with the situation.
