I'm 5'5, 130lb, currently 34b. How big should I go?
There is no single right number of cc's for a 5'5", 130-pound woman who wears a 34B — the right size is chosen from your anatomy, not your statistics. The starting point is the width of your breast: an implant whose base matches your chest tends to look natural, while one too wide or too narrow looks wrong no matter the volume. Your tissue matters too — how much natural padding you have to cover the implant and how much your skin will stretch. In our practice the process looks like this: you bring goal photos, we measure, you try sizers in a bra, and in some offices 3D imaging previews the result on your own torso. Most patients starting from a B who want a moderate increase land in a fairly predictable range, but the exact number should come from an exam, not the internet. See a board-certified plastic surgeon and try the sizers — it is the closest thing to a test drive.
Clinical Context
Implant size isn't just a cup-size number — it's about matching your chest width, tissue thickness, and skin elasticity. Wider implants than your natural breast base can look unnatural or cause rippling; too little tissue coverage can make edges visible. Profile (how far the implant projects) also changes how much volume looks right on your frame. Because bra sizing varies by brand, cup size is a poor way to estimate final volume — an in-person exam and sizer trial give a far more accurate picture than any formula.
