I had 620 & 685, they really don’t look that big. My last implants were 400, I remember looking at the implants thinking they were massive but once they were in I was disappointed. Go with the bigger ones or you will get the dreaded boob greed lol! Ps if you get the m&s bra, get a back size up to allow for swelling, mine was far too tight few days after op, 5 days later it fits like a dream! X
