Buying Guide: Key Purchase Considerations
- Weight and balance: heavier forms (around 400 g) provide pronounced fullness, while lighter options (200–300 g) offer subtler silhouettes. Choose based on your natural chest and desired look.
- Shape and back design: triangle, concave back, and axisymmetric shapes influence how the form sits against skin and fits in bras or prosthetic pockets.
- Material: medical-grade silicone feels closest to real skin; alternatives like sponge/cotton blends offer more breathability and flexibility but may differ in feel.
- Wear method: some forms’re designed to be worn inside a bra pocket; others can be adhered with skin-safe glue. Consider daily wear versus occasional use.
- Left/right distinction: most forms are symmetrical, but some are designed with defined left/right shapes for best fit after mastectomy.
- Maintenance: silicone forms are generally easy to clean with mild soap and water; follow care instructions to extend life.
- Ventilation and skin comfort: deeper concave backs can improve airflow; proper fit reduces discomfort and skin irritation.
