If I choose an implant that has a greater width that my BWD, will that be wide enough to cover my frame? (Photo)

I would like an implant that covers my frame. I like the side boob sticking out a bit so it gives my figure that curvy figure.. so I want my implant to be wide enough that it covers my frame. Will this always be achievable if I choose an implant that has a width that is greater than my breast base width? Eg. My bwd is 12.5 and I chose a 360cc moderate that had a width of 12.75. See pic of what I mean by the implants cover the frame and is wide enough. Thank you!
