Hey, if I were you I would go for the 600cc as the jump from 560 isn’t even half a cup size, so don’t worry about them being too big
I have an american site that I used when researching my first BA as they have loads of pictures and your bound to find your size in there, you just have to dig around for a bit! Make sure you click on the silicone gel implants section and not the saline as they can give a totally different appearance

Hope this helps!
