Trulife 475 SILK supreme breast form is an asymmetrical silicone breast form that accommodates excess skin tissue in its concave back. Underarm extension fills in where tissue is missing at the axilla area. Works well for bilateral mastectomy. 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 colored pigment produces a color that blends well with various skin tones. Fit: Shallow to Average. Sizes: 1-14. Choose right or left. (See Trulife Naturalwear's breast forms sizing chart).
