If it is a kilt - then it is a kilt - in my book anyway, and should conform to the handedness of the standard garment.

A kimono for instance, is almost always folded kiltwise, and only folded the other way on corpses.

As I sometimes wear a kimono with a kilt it would look rather odd to have them closing on different sides.

There might be a visual conflict if a kilt was to be worn as part of a suit with a double brested closing - though on most women it would not be well proportioned in the first place so might never, with due consideration, ever be done.

If making a kilt for another woman I'd make the pleats as standard, unless she wanted them to point the other way, and similarly do the apron on the left side, to go over to the right, unless it was wanted the other way.

I make clothes and long ago learned that the customer dictates the style, the colour and the time scale. They pay for it, so they get to chose.
