because they can t tell. there s kind of like where there s shaving marks? it looks life-like. the cosmetic cover color-matched to her skintone, down to the freckles and creases on her heel. she now has four prosthetic legs. this is my waterproof leg. i wear this one in the shower. this one for running, another for flats, another for high heels. i kind of feel like my old self again. reporter: she had no idea she would get this far, under aviva drescher walked into her room. she walked in with high heels and skinny jeans, and i couldn t tell which leg was real and which wasn t. it really helped me think i m ready to do it. reporter: of course the priority is how will i walk? but beyond that, it s sort of a female rite of passage. how am i going to feel pretty?
