Breast Form Fitting Guide

Comfortable, shapely, and with a natural feel, that’s what We Wear Boost prides itself on. The key ingredient to achieving this feeling is to choose the right size for you.

Breast Prosthesis Sizing Chart

Please view our up-to-date breast form sizing guide below.

Our six existing sizes are split across two ranges – Shape & Curve. You’ll find our Extra Small, Small, and Medium in the Shape range. Our Medium-Full, Large, and Extra Large make up the Curve range.

  • Hand Washable 
    The Boost breast form is hand washable. We recommend you wash it as often as your clothes.
  • Up-Cycle
    The silicone your Boost breast form is constructed from, is the reason your breast form is so strong and durable – but this also makes it hard to recycle. So at the end of the products life, we will take it back and use it for something else!

Popular Breast Form Fitting Questions

How do I know what size breast prosthesis I need?

At Boost, we understand that finding the right size breast prosthesis is crucial for comfort and confidence. To determine your ideal size, take these four steps: check your bra size, consult our size chart system, consider your personal preferences (lightweight, daily wear, special occasion, exercise), and seek professional fitting advice.

How do you fit a Boost breast form?

With Boost it could not be simpler. No adhesive is required – our lightweight silicone breast forms are ready to pop into place straight away. Depending on your outfit, you may wish to place your Boost breast form into a bra (this doesn’t have to specifically be a mastectomy bra), however when keeping active, for example, swimming, the Boost breast form can be inserted straight into the swimming costume. 

Check out our new collaboration with Zoggs swimwear, who have created the perfect mastectomy swimming costume to help you feel your best.
