Breast Form Sizing

Breast forms or partials are prosthetic devices designed to mimic the look and feel of natural breasts. They can be used by individuals who have undergone mastectomies, lumpectomies or have congenital breast anomalies. Here are some tips for how to properly find a breast form or partial size:
  • Determine your bra size: Knowing your bra size is the first step in finding a breast form that fits well. Use a measuring tape to measure the circumference of your rib cage just below your breasts (the band size) and the fullest part of your breasts (the cup size). We always provide fittings at no cost in store.
  • Consider your lifestyle: Think about your daily activities and how much support you need from your breast form. If you lead an active lifestyle, you may need a breast form that allows for more air flow to keep you cool.
  • Choose a shape: Breast forms come in different shapes, including teardrop, oval, and triangular. Consider which shape would best mimic the natural shape and fullness of your breasts. We have numerous forms that can cater to your individual needs.
  • Select a material: Breast forms can be made from silicone, foam, or other materials. Silicone is the most realistic and durable option, while foam is lightweight it is not likely to be equally balanced with the remaining breast for those with unilateral mastectomies.
  • Try on different sizes and styles: It's important to try on different sizes and styles of breast forms to find the one that fits and feels most comfortable. 
  • Consult with a professional: We always recommend consulting with one of our certified fitters who specializes in prosthetic breasts and partial forms. We can help you find the perfect breast form for your needs and provide tips on how to wear and care for it.
