Hi Rayna, i wasn’t flat chested i started with an empty B but just wanted to say that in all the research i have done some of the best outcomes i have seen have come from washboard flat chests, i don’t know why that is for sure but i would think it really goes in your favour if they are simply placing implants as appose to dealing with existing problems that come with tissue such as assymetry of volume, drooping, empty skin, poor quality tissue from feeding or weight loss/gain etc….so i really wouldn’t worry too much, hope your surgery is a great success and you have a smooth recovery xxx
