The kimono is easy to fake if you have a long silk robe and a nice satin or silk scarf. Try the thrift store to find these items. Fold the front of the robe closed and wrap the scarf around your waist a few times, keeping it as wide as possible.
Any shortcomings in your home made costume can be made up with a nice face full of makeup. Paint your face and neck white, covering all skin that is not covered by the neck of your robe. Power won't look right here, you really do need to get costume makeup for this one. Look for packages at the store for clown face paint, they always come with lots of white.
Highlight your eyebrows with an eyebrow pencil or mascara brush, just to make them look darker if necessary. Red lipstick should be applied to the upper lip and middle of the lower lip. Pat the rest of the lower lip with white makeup.
Geisha walk around on wooden clogs that are raised with two blocks of wood on the bottom. You can fake this with a little foam. Go to the craft store and buy a few sheets of foam that is used for art projects. Cut 2" wide strips of foam and measure them against the bottom of a pair of flip-flops and cut to the width. Start to layer the foam strips by hot-gluing them together, like a hot-glue and foam sandwich. Once they are about an inch or two high (the higher the more difficult it will be to walk in them) hot glue them to the bottoms of the flip flops.
Wear white socks with your flip flops, these are to imitate the traditional 'tabi' socks. Don't wear any rings, carry a parasol and make polite conversation.
