Pick a breast by your frame, not a number.

Why “I want to be a C” is an unanswerable request

Cup size is a garment measurement that varies by brand, band and continent — it is not a surgical spec. Implants are measured in cubic centimeters of volume and millimeters of width and projection. The translation between the two runs through one thing only: your anatomy.

The measurements that decide

Base width — the width of your natural breast footprint — sets the diameter an implant can occupy without spilling into the armpit or the midline. Soft-tissue pinch — how much of your own tissue covers the implant — decides how much device can sit under it before edges show or ripple. These two numbers do more to determine your result than any number you bring in.

Within your width, profile is the real style decision: the same volume can sit lower and softer or rounder and more projected. This is where “natural” versus “done” actually lives — not in the CCs, in the shape the CCs take.

The natural-look spectrum is real — and personal

Some patients want a result no one can name; some want a result no one can miss. Both are legitimate briefs. What matters is that the brief is explicit: sizers in the office, photographs of frames like yours, and a surgeon repeating your goal back to you in anatomic terms. If you’re hearing about the athletic, proportion-first version of this operation online, we wrote about that conversation too — it’s in the Journal.

The part most sizing guides skip

Implants are devices, and devices are maintained. The FDA’s current patient labeling covers rupture screening and device-associated risks — read it once from the source, linked below, not from a forum. Screening schedules and the realistic revision horizon belong in your consult in plain numbers. A practice that volunteers this is planning your decade, not just your operation.
