With the flower picking classes, and feminine classes in general, it might've been used for training Kunoichi in the art of infiltration and subterfuge. A "how-to-fake-being-a-lady class".

But obviously Kishi went into a completely different direction from any "ninja infiltration" so he swept that concept under the rug as it served no story purpose.
