skirt

so a skirt would be a spodnica

spódnica «część wierzchniego stroju kobiecego od pasa w dół»

So being a Scot I was aware of spodnica

and used męska spódnica szkocka

on many an opportunity

still it is nice to know

that there are differences

between a skirt and a dress

similarly spódnica and sukienkę

Your right Jack
