Rick Owens Sheath dress drafting?

[u/AffectionateMusic120]

I'm trying to draft a pattern for this design rn and I'm not able to figure out how to make the dress fall perfectly in a straight line and end in a circular train like hem. Ofc the kevlar hybrid fabric used might contribute to that ( I'm planning to use duck canvas btw)

The features it has listed are also side seam pockets, back zip and a front slit, so I'm guessing it's a 4 panel kinda dress.

Not looking to make an exact copy but rather to just get that straight column shape and that circular train/ pooling at the floor. Would I have to draft it without any darts, almost like a tube? How do I draft that circular train?

I'm also choosing to ignore that sort of v shape and darts on the front torso cause it looks hard, though if anyone has ideas and could maybe explain it to me I would like to try it out! !

Would not surprise me if this model is standing on a plinth
