Within the pages of this Almanac you will not often find me mentioning the form of dress the monsters that call Minas home wear. This is for the simple reasoning of time and there is simply too much variety to be absolute about such. Though it is to be known that most monsters have the capability of 'creating' clothing through the manipulation of their manos. This ability appears to be innate and inherent from birth. There are certain species such as the arachnae who prefer to weave their own clothing instead of forming it through the manipulation of manos.
This clothing acts much like regular clothing and can be manipulated or moved without dissipating. Even removing the article will not lead to an immediate destruction of the garment, instead should the monster decide to recreate the garb, the removed garment will then secede from existence and reappear on their body.
Note, while yes there is plenty of variety to a species choice in wear, species will generally wear similar types of apparel depending on their personality. The modest meeker type wear more body concealing clothing, the more licentious sadistic prefer leather and revealing clothing.
[AKA, until I get better at drawing or can hire someone to make the illustrations, clothing isn't important and something I'll figure out in the future.]
