My boobs look too wide apart (Photos)

Thank you for your question and for your photographs.  In general in the case of submuscular augmentation.  Most doctors will place the implants this close to the midline as possible.  Generally , we will not violate the insertion of the pectoral muscle on the sternum.  If the muscle is elevated the implants can, come too close together and cause breadloafing.  Over time, the force of the muscles pushes the implants out under the arms.  So when you lay back the implants tend to go to the side.  Natural breasts do this as well.  From your photos, with these exceptionally large implants, it looks like your surgeon did a good job of bringing them as close together as possible without giving you synmastia.  Cleavage, will still require a strong and supportive push up bra with these large implants. It's important to wear a bra with the size implants because gravity will win eventually.   Best wishes.  Hope this makes sense.  

Your implants are very large for your frame so they will go sideways. There is not much space to move them together without causing more problems.

Unfortunately I think that your implants are way too big for your frame.  The  sheer weight and size of the implants will continue to  weigh down your breasts creating  a more ptotic breast .  There's no way to get perky breasts with such a large implant. More than likely you needed a much smaller implant with a mastopexy.
