💚🍉💚 New Colour Drop 💚🍉 💚
Your go-to pocketed mastectomy tank tops just got a fresh update with two new colours: Emerald and Watermelon. These vibrant new shades are designed to brighten your wardrobe while delivering the same trusted support you love.
Each tank features a built-in pocketed bra with secure pockets to hold your breast prosthesis comfortably in place - no extra bra needed and no bra straps showing. Smooth, supportive, and easy to wear, they’re perfect for layering or wearing on their own.
Looking for more of a neutral look? This top is also available in Black, White, Beige, and Mocha.
Style you’ll love, coverage you can trust. This pocketed mastectomy swimsuit features a striking teal botanical print and a higher-sitting keyhole neckline that discreetly conceals chest concavity and prosthetics. With a smooth, supportive fit and secure internal pockets, it’s designed to help you feel confident, comfortable, and carefree in the water.

A classic swimsuit look, but with a modern vibe. The higher neckline covers any breast surgery concerns such as concavity, scaring, or a port, holding tight to the body as you lean forward. The sheer middle piece hits right where you want it in the middle of your torso, giving you an hourglass figure and visually breaking up the one-piece suit style for a younger, more modern look. Available in black and in sizes 12B (bra size 38B) – 16D (bra size 42D).

This past weekend we celebrated Mississauga’s Legends Row inductee, the incredible and formidable Anne Parker. 💖
Anne Parker is a trailblazer whose impact on the global breast cancer community will continue to be felt for generations. She was one of the first women in Canada to test positive for the BRCA1 gene mutation, after years of pushing for research into a hereditary cancer gene. Her story, shared in her book Annie Parker Decoded and the award-winning Hollywood film Decoding Annie Parker, has brought hope and inspiration to women worldwide. Her charitable work continues to inform and educate the future of breast cancer care for those with this hereditary gene.
Congratulations to the other incredible Legends Row inductees as well .hou

Dianne’s Mastectomy opened in 1985. Since that time, Dianne’s has provided quality post-mastectomy products and personal support to women in Toronto, the GTA, and surrounding areas.
At Dianne’s you will find a comfortable and private setting. Fittings by appointment allow you one-on-one time, privacy, and individualized attention. We carry the largest selection of post-mastectomy bras in Ontario and are continuously expanding our lines to serve you better. We are one of very few across Canada licensed to custom make breast prosthetics and are also the area dealer of at-home lymphedema therapy machines.
Working closely with the Canadian Cancer Society, area doctors and hospitals, as well as many related agencies provides you with the best possible care and most up-to-date information on breast health.
Products We Carry
Breast Prostheses
A breast prosthesis (plural: prostheses) is the replacement breast you will use following your surgery. If you have had a full mastectomy you will require a full breast prosthesis. Rather, if you have had a lumpectomy you may require a partial prosthesis. Many women who have not had surgery may also require a partial breast prosthesis due to genetic or uneven breast development.
Mastectomy Bras
All of the bras we carry are post-surgical, which means you will not be restricted to just one section of our store. Pre-pocketed and supportive, post-surgical bras allow for the weight and shape of your new breast prosthesis while maintaining a high level of comfort. As you will soon see, our vast selection of bras will have something to satisfy your individual needs and personal tastes.
Compression Garments & Machines
Compression garments for both men and women are important in the treatment of Deep Vein Thrombosis (DVT) and lymphedema. We carry compression armsleeves, both dress and sport compression stockings, as well as lymphedema management machines.
Accessories
You will find a variety of accessories in our office, including bra accessories and garments for directly after surgery.
