I'd go to Pier One and get a bamboo pole (more traditional) and thread it thru the sleeves. Hang it from curtain brackets for a nice look or just from inconspicuous finishing nails. Usually kimono are hung displaying the backs, which tend to be more ornamental, but that depends on the kimono. You might need to use some straight pins (if you have dry wall) to secure the corners to keep it shaped nicely. Hang it out of direct sunlight, and consider this a short term display if it's at all valuable (which many antique kimono are.) If it is, you might someday want to have a custom plexiglass box frame made -- that's the nicest option to protect it and display it. Alternatively, just WEAR it some time when your mother-in-law is visiting -- they are gorgeous as evening wear!
