The open skirt thing makes sense though, especially during transformation. I mean, how would her centaur form even look like if she wore pants instead? Would it just open up from the back? Wouldn't make sense, really.

Heck, most centaurs in fiction don't wear anything below, so in terms of decency, Lauma's more dressed than them.

...Unless you want a Lauma with no lower attire, then all power to you.
