This is something myself and a few different groups of mine have discussed time and again now. Elder Scrolls in general has pretty much entirely overlooked cloaks as something that even exists. Luckily mods exist in other games such as Skyrim to fix that little issue, but obviously there's nothing to fix that in ESO.
Cloaks seem like something that would be very easy to implement, maybe with some tweaks here or there for different kinds (like thicker fur cloaks for nords and orcs up in cold northern areas, but more linen cloaks for places like Elsweyr or Valenwood).
Cloaks could be equipped the same as things like disguises and guild tabards into the Appearance slot on characters as more aesthetic pieces rather than gear slot pieces.
