From the photo, which is gorgeous, and Mike's description of size and perfume I'm guessing it's a pink variety of "Stargazer". They're Asiatic lilies and always have a lovely perfume and those long stamens. Mike, watch the pollen, it stains things and they absolutely drip with it.
You can grow those yourself, bulbs are obtainable any good garden centre or mail order. They need good drainage, so put some grit or something in the planting hole and they'll come up year after year. Unless you disbud you won't get flowers quite that size, but still a good size, about 4 inch diameter.
