Thanks for including photos! Yours clearly show your concern with breasts that are widely spaced on your chest wall. Breast enlargement with implants will give you larger breasts, and the widest profile implants (least projection for a given volume) will yield the closest cleavage.To some extent, this is size-related. Obviously, large(r) implants have wide(r) base diameters, and when centered properly beneath your nipple/areola complexes, will give a certain cleavage width. The larger the implants, the closer they get in the center, and also the more "side boob" you will have. For widely-spaced breasts, it may take fairly large (even with moderate profile) implants to give you "close" cleavage. Maybe larger than you wish. But small(er) implants still need to be centered beneath your nipples--you can't simply take small implants and put them close together in the cleavage area, or else you get "wall-eyed nipples" that point sideways! Not a good look at all!Since you want only a cup and a half or so of enlargement, this involves implants that are in the 400cc size range (or thereabouts). 420cc Allergan silicone gel moderate profile implants have a base diameter of 14.0cm (the 390cc implants have a 13.6cm base). This would not give you a cleavage that is close, deep, or sharply defined, but you would have enough breast volume to now fill a beautiful push-up bra that can accomplish your goals.Even moderate profile 650cc implants (that would add about 2 1/2 cups to your present size) have a diameter of 16.0cm, but 2cm more per side equals about and inch and a half "narrower" cleavage. But you might now have larger breasts than you wish. Consultation and compromise may be in order here, and the best way to achieve your best cosmetic outcome would be to obtain several consultations with ABPS-certified plastic surgeons who do lots of breast surgery.
