Realistic Breast Forms for Crossdressing & Everyday Wear

Our best-selling Original Silicone Breast Forms are designed to provide a natural-looking bust with realistic weight, shape and softness. Featuring a triangular design, lifelike nipple detailing and flexible silicone construction, these breast forms can be worn beneath supportive bras and everyday clothing to create your preferred silhouette. Available in pair weights ranging from 400g to 2400g, they offer a variety of bust sizes and levels of projection to suit different body proportions. Whether you're exploring crossdressing underwear, transitioning or looking for realistic breast inserts for regular wear, our Original Breast Forms provide a versatile starting point for finding your preferred shape and size.

How to Choose the Right Breast Form Size & Bra

Finding the right breast form size depends on your underbust measurement, chest shape, preferred cup size and desired level of projection. Unlike traditional bra sizing, breast form weight doesn't directly correspond to a specific cup size, as the same pair of forms can create different results depending on your body proportions.

To simplify the process, our free MTF Bra & Breast Form Size Calculator estimates your Australian bra size and allows you to compare how different breast form weights may affect your finished bust size. For additional sizing and fitting advice, explore our beginner's guide to choosing breast forms or speak with our experienced fitters.

Swimming Breast Forms, Lightweight Sleep Forms & Accessories

Different occasions call for different breast forms, which is why our collection includes specialist options beyond traditional silicone inserts. Our Swimming Breast Forms feature a transparent silicone design with a textured backing that allows water to pass through, helping reduce suction beneath suitable swimwear. For relaxing at home or sleeping, our Lightweight Sleep Breast Forms feature flexible silicone bead filling and a breathable polyester outer shell, providing a softer, lighter alternative to solid silicone forms. We also offer Breast Form Pockets, featuring a sheer front and soft cotton backing to create a comfortable fabric layer between your forms and skin.
