Miim was developed by Japan's Institute for Science and Technology. They admit she doesn't have the same moves as "real" fashion models, but they say she'll get better with a little more technology.
Miim's creator compared his feelings to those he might have on his daughter's wedding day, saying he was "really nervous."
One of the real-life models who took part in the same show later observed, "If they can do the job with robots, then I'm in trouble!"
