I thought that'd be more of an ankle length skirt? At least a Google search for calf length skirt turns up images of skirts about 10-20 cm shorter than the Spring Skirt.
It's basically the same item as the Plain Long Skirt, except it lacks the bow at the waist. They dye exactly the same way. The plain version only needs one dress material to craft though, so should be cheaper to obtain.
I'd also like to mention this site, where you can find a gallery of all items for a particular slot with advanced search: https://xivstyle.com/
