Shoes should suffer fall damage :)

Outfits from the professions need to have a T2 version (or are straight up moved down to T2); give actual bonuses to it being worn (esp. you, cloth cape!), and absence of clothing needs some sort of malus to it (unless you're wanting to skinny-dip)!

Tailoring sucks, there is no longevity.

Make clothes wear out faster if you mine, dig, farm or chop trees.

Make work clothes last longer vs normal clothes if you do these gathering tasks.

Make different type of clothes for different professions so they get bonuses to that profession.

Aside from using time worn as a way when durability should increase, there is little else that would make sense to include. Perhaps it would be like tools, and only decrease when calories are expended, though the difference here being that would also include putting labor into a crafting table.
