The most common mistakes are not technical. They are mistakes of timing and of tone: fitting a woman before her chest wall has settled, putting her in a garment that cannot hold a form securely, and narrating her body back to her while she stands half dressed in front of a mirror. The garment errors are fixable in an afternoon. The tone error costs you the customer and everyone she talks to.
Post surgical fitting is not a separate trade from bra fitting, but it carries a set of specific failure points that a general fitter will walk straight into with the best intentions in the world. Below are the ones that come up most often on the floor, and what to do instead.
A note before any of it: nothing here is medical advice, and a good fitter's most useful sentence is often "that is a question for your surgeon or your therapist."
Fitting too soon after surgery
A chest wall changes shape for months. Swelling recedes unevenly, incisions tighten, radiated tissue contracts, and a woman who is still in active treatment may have weeks of change ahead of her. A permanent silicone prosthesis fitted at week three will very likely be the wrong size and shape by month three.
What generally happens instead: immediately after surgery she wears a soft, front closing garment, often supplied by the hospital, with a lightweight leisure form or fiberfill puff. A fitting for a weighted prosthesis and a pocketed bra typically waits until incisions are fully healed and swelling has settled, and her surgical team is the one who says when that is.
The mistake a boutique makes is treating an early appointment as a sale. If she arrives at week two, fit her in soft cotton, give her a leisure form, and book her back. Say clearly that this is a temporary garment and that you will refit her at no charge when she is ready. That conversation is the beginning of a ten year relationship.
The insurance timing trap
Many insurance plans, including Medicare Part B under durable medical equipment provisions, cover external breast prostheses and post mastectomy bras on a defined replacement schedule, with a prescription from the treating physician. Fitting her prematurely can burn a covered replacement on a garment she outgrows in eight weeks. Ask what her plan's replacement interval is before you fit the permanent form, and coordinate with the prescribing office.

Choosing a bra that cannot be pocketed properly
Not every pretty bra can hold a prosthesis. A weighted silicone form needs a pocket that is anchored to a stable cup, and it needs the cup to have enough structure that the form is not visibly shifting when she raises her arm.
What fails when it is pocketed:
- Thin unlined stretch lace. The cup deforms around the form and the outline shows.
- Deep plunges and low balconettes. Insufficient upper coverage means the top edge of the form can lift away or be visible at the neckline.
- Very stretchy molded cups without a firm cradle. The form migrates toward the underarm through the day.
- Bras with a very narrow band. A weighted form on one side pulls the band, so she needs width to distribute it.
What works: a bra with a full or three part cup, a firm underband of decent width, a stable cradle, and either a factory built pocket or a cup lining a seamstress can convert. If you offer aftermarket pocketing, be honest about which of your styles can take it and which cannot, and price the alteration up front.
Ignoring drain and scar placement in the band
Scar tissue does not tolerate pressure and friction the way intact skin does, and a band seam sitting directly on a mastectomy scar or a radiated area will be intolerable by mid afternoon even if it felt fine in the fitting room.
Before you pull anything, ask where her incisions are and whether anything is tender. Then check three specific contact points on the garment: the underband seam at the side body, the underarm edge of the cup, and the wire terminal if there is a wire. If any of them lands on scar, change garments rather than trying to talk her into tolerating it.
Wire is not automatically forbidden after surgery, and plenty of women wear a wire comfortably on a reconstructed or unaffected side. But the wire has to sit on the ribcage and the breast root, never on the scar line, and the answer to "can I wear a wire" belongs to her surgical team, not to you.
If she has drains in place, she should not be in a fitted bra at all. That is a soft camisole with a shelf and an internal drain pocket, and if you do not stock one, know who locally does.

Confusing a leisure form with a weighted prosthesis
These are two different products with two different jobs, and selling the wrong one is a quiet but consistent error.
| Leisure form | Weighted silicone prosthesis | |
|---|---|---|
| Material | Fiberfill or foam, very light | Silicone gel, weighted to approximate breast tissue |
| Best for | Sleep, immediately post op, swimming, low activity | All day wear, especially unilateral |
| Balance effect | None meaningful | Counterweights the remaining side, reduces shoulder and neck strain |
| Typically insurance covered | Sometimes, on a separate line | Yes, with a prescription, on a replacement schedule |
The point that matters most: a woman with a unilateral mastectomy who wears only a light leisure form all day is carrying asymmetric load on her spine. Many report shoulder, neck and back discomfort as a result. The weight in a silicone form is the function, not a side effect of the material.
Assuming a symmetry that is not there
Fitters trained on standard sizing reach for a single band and cup and expect both sides to behave. After surgery they often do not, and not only in the unilateral case. Reconstruction on one side may sit higher, firmer and rounder than natural tissue on the other. Bilateral reconstruction can still be unequal in projection.
Fit the larger or less compressible side first, then correct the other with a partial form, a shaper, or a fuller cup with a shell. Do not try to squeeze the fuller side into a cup sized to the smaller one. Record which side is which and by roughly how much, because six months later neither you nor she will remember.
Ask her also what she wants the finished silhouette to be. Some women want visual symmetry under clothing above everything. Others are past that and want comfort and a garment that stays put. Both are correct, and you cannot guess which she is.

Talking about the body instead of the garment
This is the mistake that does the most damage and costs nothing to fix. Fitters are trained to narrate: "you are spilling here," "there is a gap here," "this side is smaller." That habit, in this fitting, lands very differently.
Move every observation onto the garment.
- Not "your left side is smaller." Instead: "this cup has more room than we need on this side, let me bring in a shaper."
- Not "that scar is going to be a problem." Instead: "this seam sits where you do not want pressure, so let me find one built differently."
- Not "you have lost a lot of volume." Instead: "we are looking for a form in this profile, and I have two options."
Practical room rules that go with it: offer to step out while she changes and knock before returning, ask permission before you touch, keep the room genuinely private with a solid door or a heavy curtain, and offer her the chance to bring someone with her. Ask her, do not assume, whether she wants the mirror facing her while you work.
Give her time. A post surgical fitting is a sixty to ninety minute appointment, booked as such, not squeezed between two walk ins on a Saturday.
Building a referral relationship with local surgical offices
Most boutiques wait for these customers to find them. The ones who do this work well go and introduce themselves.
- Identify the offices. Breast surgical oncology practices, plastic and reconstructive surgeons, oncology navigators at your local hospital, and lymphedema and oncology physical therapists.
- Bring something useful. A one page sheet with your address, hours, appointment length, what you stock, what insurance paperwork you handle, and a direct phone number for their navigator.
- Get the billing right. Understand what a prescription needs to say, whether you bill insurance directly or provide a detailed receipt for her to submit, and what the replacement interval is under the common plans in your area. Nurses refer to the shop that does not create work for them.
- Close the loop. When a referred patient is fitted, thank the office. Referral relationships are maintained by acknowledgment, not by brochures.
- Train a named fitter. Manufacturer certification programs exist for prosthesis fitting, and having one certified fitter on staff with a name the navigator can ask for is worth more than any advertising you could buy.
What to carry out of the fitting
Everything above depends on memory, and memory across staff and across years is the weakest link in this work. She should never have to re-explain her surgery, her sides, her scar placement or her form size to a second fitter.
Keep it in her record: surgery type and date, which side, form size and profile, which styles pocket well on her, the seams that cannot sit where they usually sit, and her insurance replacement date. FitRoomLog holds exactly that, alongside a restock alert when her size and style come back in stock, so the next appointment starts with recognition rather than with questions she has already answered.
