The new spiral skirts in Simplicity, Butterick, McCalls

Was online t'other day looking at the big three websites and noticed some spirals. 

Simplicity 2416 and Butterick 5042 both look really cool! If I hadn't already made up my own I would totally buy one of these.

McCalls 5056 caught my eye but it's not a spiral at all.  They've colored the illustration to look like it is. Isn't that silly?
