5 Signs Your Mastectomy Bra Doesn’t Fit Properly (And How to Fix It)

by glen james

After surgery, your body undergoes significant changes, and a bra that fit perfectly two months ago may no longer provide the support you need. A poorly fitting pocketed bra isn't just uncomfortable—it can cause skin irritation, neck pain, and even affect the lifespan of your breast prosthesis.

To help you feel your best, here are 5 signs your bra isn’t quite right and our top mastectomy bra fitting tips to fix them.

1. The Underband is Riding Up

If you find yourself constantly pulling the back of your bra down, the band is too large. The underband provides 80% of a bra's support; if it’s loose, your shoulders take the strain.

The Fix: Go down a band size (e.g., from a 38 to a 36). Remember, when you go down a band size, you usually need to go up a cup size to keep the volume the same.

2. Gapping at the Top of the Cup

Do you see space between your skin and the fabric at the top of the cup? This is a common issue when asking how should a pocketed bra fit. Gapping often happens if the cup is too large or if the breast form is too small for the pocket.

The Fix: Try a smaller cup size or adjust your straps. If the gapping only occurs on the side with the prosthesis, you may need a fuller-profile breast form.

3. The Center Front Doesn't Sit Flat

The "gore" (the center part of the bra between the cups) should sit flat against your breastbone. If it’s lifting away, it’s usually because the cups are too small, forcing the bra away from your body.

The Fix: Increase your cup size. A flat center front ensures the pockets hold your prosthesis securely against your chest wall.

4. The Breast Form is Shifting

If your prosthesis is sliding toward your underarm or falling toward the center, the bra isn't providing enough "encapsulation."

The Fix: Look for bras with higher center fronts and deeper side wings. Our High-Support Mastectomy Collection is designed specifically to "lock" forms in place for all-day security.

5. Straps are Digging into Your Shoulders

This is often a sign that the straps are doing the work the underband should be doing. It can lead to headaches and "bra-strap grooving" on the shoulders.

The Fix: Tighten the underband and choose bras with padded, wider straps. These distribute weight more evenly, which is essential if you wear a weighted silicone prosthesis.

Fitting Checklist: How Should a Pocketed Bra Fit?

Before you head out for the day, do the "Two-Finger Test":

Band: Can you fit two fingers under the back band?
Straps: Can you fit two fingers under the shoulder strap?
Pockets: Is the prosthesis sitting level with your natural breast?

Expert Advice: We recommend a professional fitting every 6 months post-surgery. If you are measuring at home, use our Orchid Boutique DIY Fitting Guide to get the most accurate results.
