Google isn't helping me so I come to ask the experts.

So, I see a bunch of different names for said item, what's the universal term?
Is it:
Ladies Kilt
Women's Kilt
Kilted Skirt
Plaid skirt (yup, our lazy incorrect American term for tartan, I know)
Mini kilt
unisex kilt
tartan skirt
"Ye daft lass, only men can wear a true kilt"
ladies kilted pleated skirt
skirt kilt (in which case I'm nick naming it a Skilt... like Jorts (jean shorts), Shants (short pants), or Manpris (capri pants for men))
or
"It doesn't matter as long as it looks nice"

-from "the tartan pleated skirt" wearing gal
