Was told I'd end up "about a DD" and my bra drawer completely disagrees. Does cup size after implants mean anything?

Ten weeks post op and I've finally gone bra shopping properly, which I'd been putting off, and I've come home confused and slightly annoyed.

At my consultation I asked the one question everyone asks, what cup will I be, and got "you'll probably be around a DD". Fine. I went in today, got measured by the shop, and was told 32E. Then in a different shop, 34DD. Then I tried on a 32F in one brand that fitted better than either. Meanwhile two of my own old 32C bras from before still do up, they just look ridiculous.

So which of these is my actual size? Did my surgeon get it wrong, or is the shop wrong, or is the whole cup thing basically made up? I ordered a load of pretty bras online in a DD before surgery, thinking I was being organised, and now I have a drawer of expensive mistakes. Bit sore about that.

Nothing was wrong and nothing was made up, they're just different systems pretending to be the same one.

Your surgeon put a fixed volume in cc into your chest. A bra cup is not a volume, it's the difference between your ribcage measurement and your bust measurement, in a shape decided by whichever brand cut it. So the same breasts genuinely are a 32E in one label and a 34DD in another, those two are the same cup volume with a different band, and a third brand will do something else entirely because their cut is deeper or shallower.

The pre-buying pretty bras thing, though. Everyone does it and everyone regrets it. Don't buy anything you can't return until you're properly settled.

Adding my mistake to the pile: I bought six bras at week 7 in a size that fitted perfectly at week 7. By month 4 the shape had changed enough that the cups gaped at the top and dug in underneath. Nothing had grown or shrunk, it had just redistributed as everything settled downward.

I now own six week-7 bras and a lot of feelings about it.

All of them, and that's the honest answer rather than a dodge, so let me explain why we're so cagey about cup letters in consultations.

What we plan with is volume and dimensions: implant volume in cc, the base width of the implant in centimetres against the width of your own breast footprint, and the profile, meaning how far it projects for that width. Those are measurable and they're the same numbers whichever country you have surgery in. A cup letter is not a property of your body at all, it's a property of a garment, derived from a band measurement and a bust measurement and then adjusted by the manufacturer's own pattern. There is no international standard forcing two brands to cut a DD the same way, which is exactly what meglifts found in an afternoon.

Two practical points. First, when a surgeon says "about a DD" they are translating volume into the language you asked the question in, as a rough guide, not a promise, and the same implant on a different chest wall produces a different letter. Second, the timing matters more than the letter: the shape keeps changing while swelling settles and the implants find their position, which is why being measured at week seven produces a bra that fits at week seven and lies to you at month four. Most of us suggest waiting until things have genuinely settled, commonly around the three-month mark and sometimes longer, before spending money on anything that isn't your post-surgical garment. Your own surgeon's timeline for coming out of that garment and into normal bras is the one to follow.

The site's guides to how sizing is actually done in cc and profile and what to wear while everything settles cover both halves of this. And for anything that feels wrong rather than merely confusing, a fit problem that comes with pain or a change in shape is a question for your surgeon, not a shop assistant with a tape measure.

The bit nobody says out loud: I stopped caring about the letter the moment clothes started fitting the way I wanted. That was the actual goal all along, the letter was just the vocabulary I had for it before surgery.

Update, mostly so the next person searching this finds something useful. I've stopped trying to have one size. I've got two bras in each of two sizes from two brands, all returnable, and I'll do a proper fitting again after my four month check like the sensible people here suggested.

The drawer of DD mistakes has gone to my sister, who is delighted and slightly smug about it.
