Well Maiko strictly speaking (apprentice Geisha)
One of the workshops we do is to show people how to turn a normal vintage kimono into Geisha cosplay, as well as the limitations. Only a real susohiki/hikizuri kimono with accessories can give you the full effect needed. Geisha/Maiko kimono when obtained in the vintage state are still expensive and can be fragile. This is a robust vintage synthetic kimono, which can be used in cosplay effectively without breaking the bank.
This maiko dressing demonstration was done with a wedding kimono which are widely available and a wedding obi.
