As others here said, it is too early for a revision. You should wait six months to let swelling settle and to let your tissues drape out a bit - if your swelling goes down enough, you might even want to go beyond 350 c.c.s! A general 'rule of thumb' is that 100 ccs is approximately one bra cup size, so you can figure it from there AFTER your swelling settles. And as for revising it under local, it might be possible to do it if your implants are over the muscle, but under the muscle is often too uncomfortable to do under local anesthesia. Figure this - you wil most likely need some muscle work to open the pocket a bit more to accommodate a bigger prosthesis, and, again, that's more uncomfortable. As for style: If you increase size enough, the larger HP would be wider and give you a bit more cleavage, but if you really want to be sure, you might want to change profiles to a moderate plus style. This has a little less projection, but gives you more width, which would add more cleavage and more volume up top. When it comes time for revision, you could sit down with your surgeon and look at the various widths/heights. Don't overthink it, though - it's just a few millimeters in any given direction. My personal preference is Mentor, but each company has similar shape and size variations. Good luck!
