Hi Getridofit,
Look at Brad Pitt - some say most attractive man:

He has chest too! do not think it has to be completely flat.
Why am I showing you that? so you understand your left side is actually perfect and should be like that - do not touch it in my opinion.! find a decent surgeon who will be willing to correct right side only. The surgeons thinks it is to save money!? then OMG pay him double to just do one side.
Regards
