How to Measure for a Mastectomy Bra?

A woman's bust changes throughout her life depending on events. It is therefore important to adapt her bras according to these changes. This is even more true after a mastectomy, as the size of the bra will determine the size of the breast prosthesis. But how can you know your bra size after breast surgery? And how can you tell if a bra suits your body shape? Here are all our tips on the topic.

Today, it is estimated that around 75% of women do not know or do not wear the right bra size. Yet, an ill-fitting bra can cause everyday discomfort such as irritation, injuries or even shoulder and back pain, and can also make the silhouette less harmonious.

How do I know if my bra is not the right size?

A well-fitted bra is one you don’t feel throughout the day. If it bothers you, hurts you, or if you can’t wait to take it off at the end of the day, it’s likely not the right size anymore.

  • You have irritation or injuries on the shoulders, ribs, or back.
  • Your breast seems to spill out of the cup.
  • There is a “gap” between the cup and the breast, or the cup wrinkles.
  • You tighten or loosen the straps to the maximum.
  • The back of the bra rides up.
  • You need to add an extender.
  • The bra slips and needs to be pulled up during the day.
  • You are eager to remove your bra in the evening.

Before choosing your bra and breast form, you will need to measure yourself to know your correct size.

Band Size (Under Bust)

Measure under your bust, across your ribcage and around your back under your arms. You will get your band size.

Cup Size

Measure the non-operated side by placing the measuring tape at the same level as your nipple. Start from the sternum and stop at the middle of your back. Multiply by 2.

You now have your cup size.

Tips:

Here are some tips to make sure you measure correctly:

  • Keep the measuring tape flat and horizontal, neither too tight nor too loose.
  • Stand straight.
  • Do not inhale.
  • Always measure yourself while wearing a soft bra.

How do I know if my new bra fits?

When trying it on, pay attention to several details.

Straps: They should be adjusted at shoulder blade level. Most of the support comes from the band (the back), not the straps. Contrary to popular belief, very tight straps do not provide better support. They should rest on your shoulders without slipping or digging into the skin.

The back band: You should feel comfortable with the hook on the second row. Like the straps, the band should gently touch your skin. Ideally, you should be able to fit one finger between the band and your back. The back band must stay aligned with the bottom of the cups and should not ride up.

The cups: Your breast should neither spill out nor float inside the cup. The fabric should rest gently on the breast without cutting in. The underwires (with or without wire) should not rise up or dig into the skin. Please note: band and cup sizes may vary slightly depending on the brand and model. Not all styles suit every body type. Take the time to try on and check yourself from all angles to find THE model that fits best.
