If you've already downloaded the mod, redownload the new version. The old one I forgot to add to a folder to put into mods, though, if you did know how to install mods, you would have probably done it already. If you do have a mod folder for it, I don't think you need to download it again, cheers!

What's this?

It's a set of black clothing - Boots, Hose, Chausses, Gloves, Doublet, Short Doublet, Pourpoint, Coif, two Tunics, a Cotehardie, Hooded Scarf, Short-sleeved Pourpoint, and Two Hoods (up)
It's made using in-game assets, but with unique item ID's, so it shouldn't interact with or effect any other armor in the base game.

Where do I get it?

All tailors should sell it, if you can't see it in their shop, try waiting a day or two for the inventories to reset. (Should work, haven't tested the shop yet although I did update the .xml file)

Installation

Extract the .zip to your mods directory (/steamapps/common/KingdomComeDeliverance/mods if you're using the steam version)

Compatibility

Without the use of a mod merger, this mod will conflict with any other that makes changes to; armor.xml, armor2clothing_attachment.xml, clothing.xml, equippable_item.xml, item.xml, pickable_item.xml, player_item.xml, shop_type2item.xml, English_xml.pack

Also added a file that contains my other mod that puts all hoods up (Again correct mapping for square pattern hoods) as well as Brandon17's CR-AP mod.
