What Is a Pocketed Mastectomy Bra? How the Breast Prosthesis Pocket Works
A pocketed mastectomy bra is a bra with an extra fabric pocket inside the cup that can hold a removable breast prosthesis, also called a breast form.
Instead of placing the breast form directly inside an ordinary cup, you slide it into this inner fabric layer. The pocket helps keep the form positioned inside the bra during everyday movement.
The pocket is useful for people who prefer extra breast-form security, but it is not something everyone who has had a mastectomy must use.
Pocketed bra = outer bra cup + inner fabric pocket + optional removable breast form. The breast form sits inside the pocket rather than being sewn permanently into the bra.
Where is the pocket in a mastectomy bra?
The pocket sits on the inside of the bra cup. It is made from an additional layer of fabric with an opening through which a breast form can be inserted.
Pocket shape and opening position vary by bra. The opening may sit toward the side or another edge of the cup, so always check the construction of the particular style you are wearing.
How do you put a breast form into the pocket?
The exact method depends on the breast form and bra design, but the basic idea is simple: the prosthesis is placed through the opening and positioned inside the fabric pocket.
- Find the pocket opening. Turn the cup slightly so you can clearly see the extra inner fabric layer.
- Insert the breast form gently. Follow the orientation recommended for your particular prosthesis rather than forcing it through the opening.
- Smooth it into position. Make sure the form sits comfortably within the pocket and is not folded or caught against the fabric.
- Put the bra on and adjust. Check the position in a mirror and make small adjustments if needed.
- Check it while you move. Walk, sit and reach normally to see whether the form remains comfortably positioned.
If you are still choosing a breast form, see our guide to breast prostheses before focusing only on the bra.
Why do some people prefer a pocketed mastectomy bra?
The pocket does not make the breast form permanent. Its purpose is mainly to provide a more defined place for the removable form to sit.
Does every pocketed bra hold every breast form?
Not necessarily.
Breast forms vary in shape, width, thickness and weight, and mastectomy bra pockets also vary in size and construction. A pocket should be large enough to contain the form without forcing it into an awkward position.
The bra itself still needs to fit well. A pocket cannot compensate for a band that is too loose, cups that are too small or a prosthesis that does not suit the cup shape.
Do you have to use a pocketed mastectomy bra?
No.
A well-fitting full-cup regular bra may hold some breast prostheses securely without a built-in pocket. Some people also have an ordinary bra altered by adding a fabric pocket.
And if you do not wear a breast prosthesis, the pocket may offer little practical benefit to you.

What does a real pocketed mastectomy bra look like?
The clearest way to understand the design is to look at bras that actually specify a prosthesis pocket. The examples below are from VEIMIA's current Singapore mastectomy range and both explicitly include pocketed construction.


FAQ: Pocketed mastectomy bras
What is the pocket in a mastectomy bra for?
It is an inner fabric compartment designed to hold a removable breast prosthesis or breast form. The pocket can help keep the form positioned inside the cup.
Where does the breast prosthesis go in a pocketed bra?
The prosthesis is inserted through an opening in the fabric pocket on the inside of the cup. Once inside, it is adjusted until it sits comfortably in the desired position.
Does the breast form touch the skin in a pocketed bra?
With a traditional pocketed design, the pocket fabric creates a layer between the breast form and the body. Construction varies, so check the particular bra and breast form you are using.
Do both cups of a mastectomy bra have pockets?
Many pocketed styles are designed with internal pocket construction in both cups, but designs vary. Check the product description before buying if you need a pocket on a particular side.
Do I need a pocketed bra to wear a breast prosthesis?
Not always. A well-fitting full-cup regular bra may securely hold some breast forms. A pocketed bra is useful when you prefer extra containment or more consistent positioning.
Can a regular bra be turned into a pocketed bra?
Yes. Some ordinary bras can be adapted by sewing a suitable piece of stretchy fabric behind the cup to create a pocket. A specialist fitter or alteration service may also be able to help.
