Trulife 472 SILK Plus triangle breast form is a versatile triangle that fits a variety of body types and surgery sites. Works well with both underwire and softcup bras. The comfortable back provides additional fullness and projection. SILK defines what a breast form should be; soft and natural. A new innovative skin is silky-soft and offers unparallel softness and suppleness. All SILK forms offer a natural drape not found with other breast prosthesis. Natural coloured pigment produces a colour that blends well with various skin tones. Fit: Average to Full. Sizes 1-17. (See Trulife breast forms sizing chart).
