Hi I have chosen to have anatomical implants but finding it hard to decide between the above 2 sizes. my current size is 34/36 aa ( think more like a 36) 11.7 width. weight = 146lbs ( although weight can vary between 136 -146lbs ) height 5"7.5 . I am wary if I go for the larger one the skin will have to stretch more. I currently wear 260cc gels in a bra and feel comfortable with this and want to make this look. Do you think 315 or 275 to achieve the look I want? thanks
