This mod consists of two split BodySlide modules: a FOMOD with a selection of xavbio's sleeved armor meshes, and another focused on Armory of the Dragon Cult.

Xavbio Armors Collection
Overview
This module refits many of the sleeved/pants on meshes found inside xavbio's Common Clothing (Jarl 1), Dragon (Dragonplate [Insulated], Dragonbone Mail), Iron, Leather (both Fur kilts and Leather), Imperial (Tullius, Falx, and Lord's Mail), Ancient Nord, Guards and Stormcloaks (Stormcloak and Stormcloak Officer), and Steel Retextures for HIMBO V5. Many of the pre-existing xavbio HIMBO refits were only conformed for HIMBO V4, never had refits as in Iron, Ancient Nord and Steel; or were outright missing some HIMBO V5 sliders in Dragon's case.
An additional BodySlide is provided for Forsworn Retexture's Boots of the Old Gods as it uses a different filepath and mesh to close up the right foot poking out of the normal Forsworn boots.
Common Clothing's Jarl 1 sleeves aren't "new", per se; these are actually Emperor's Robe texture swaps that are also found in ACE. If you're already using ACE in your load order, you don't need the BodySlide edits in the FOMOD's first page as the sleeved variants in ACE will use your Emperor's Robes meshes.
Normal refits for the remaining Imperial and Leather sleeved/pants on armors, and Savior's Hide are not covered here as they already have HIMBO V5 conversions in some form around Nexus. Take a look at Vanilla Armor SkirtClippingFIX for the other sleeved/pants on Imperial and Leather armors and Artistop's FSA patches for Savior's Hide.

Add-ons

• Additional BodySlides for Artificer's Yngol set and Oblivion Artifact Pack's Alvante set from Ancient Nord and Thieves Guild's retextures are available.
• The FOMOD contains an optional BodySlide set that combines the sleeved meshes with Fur Shader Armors' fur shell meshes for both Fur kilts, both Iron armors, Stormcloak Officer, Leather, and Steel armors. A few of these armors re-use the pants from the other bandit Fur armors, so I've re-used their fur shells on the Fur kilts, Stormcloak Officer, and Leather armors' pants. While the Stormcloak Officer's fur shell merely needed some adjustments so it properly cover the pelt, I've run into some trouble with getting the "Steel Heavy" fur shells to fully cover the outwards-facing fur bits on the shoulders. These two aren't perfect, but I'm more or less satisfied with how all of them look overall.
  
  • An ACE + FSA patch that edits the sleeved, FSA Jarl 1 BodySlide project and an ESPFE patch that edits ACE's sleeved Jarl 1 Armor Add-on records to use that project's new filepath (due to UV mismatching from Emperor robes and to keep the sleeved meshes separate from regular Jarl robes) is available.
  • Please note that Ancient Nord armor will not be covered by this. Xavbio uses completely custom textures for its pants, so they won't match with any of FSA's fur shells; and I don't like how the armor looked with the top and waist area's fur shells applied while the pants had none. This also applies to Artificer's Yngol set on top of the mismatching fur shells with that set's white fur textures.
  • Go here if you're looking for Fur Shaders Redux HIMBO refits.
    
• Another FOMOD add-on are sleeved HDT-SMP Vanilla Armors projects, which encompasses the sleeved/pants on Ancient Nord (+ Artificer's Yngol), Dragonplate, Fur Kilts, Iron, Stormcloak (Officer), Leather, Hide, Studded, Scaled (Horn), and the Imperial Legion (including Tullius)'s armors. I've re-used the refitted Imperial sleeves from Vanilla Armor SkirtClippingFIX here thanks to open permissions on tenjinken's part. These refits can be used with either HDT-SMP Vanilla Armors' normal or Player-exclusive variants via FOMOD options.
  
  • These refits are incompatible with the (sleeved) FSA refits; there are FSXRR HIMBO refits that can combine all three components (fur shells, sleeves, HDT-SMP) here.
  • If you're looking for sleeved 3BA refits paired with HDT-SMP Vanilla Armors' rigging and Xavbio cubemaps (where applicable), take a look at Neumeria's mod.
  • There might be slight clipping with the HDT-SMP parts into the pants. I think furexarot made most of the thigh collision boxes generously thick to combat this on the armors with skirts; still, do keep this mind if it looks weird after sniping a random bandit or Imperial soldier.
  • I don't have any plans to try stitching the HDT-SMP Tullius refit with Falx Carius' (sleeved) armor myself; it seems like the Tullius chest-back areas are much more inflated relative to Falx's Heartstone harness in HIMBO's stock refits. I'd also have to make another BS project for the Heartstone that (hopefully) slots into the harness properly...
    

Armory of the Dragon Cult
This module refits all of Armory of the Dragon Cult's armors and variants, including King-Priest's generic set and Wyrmstooth's Suleyk, to HIMBO V5.

A Konahrik's Accoutrements adaptation of this module is available. This requires Dragon Priests Retexture's KA patch as the patch modifies the KA armor records to use the same AotDC mesh filepaths for many of the named Dragon Priests' sets; thus, it made more sense for me to shift around what I already have over trying to refit KA's original meshes from scratch given their UVs aren't completely compatible with DP Retexture anyways.

Installation
Select your installed sleeved armors in XAC's FOMOD and batch build through BodySlide using your preferred preset. These BodySlides are contained under the HIMBO Xavbio (HDT-SMP) category for ease of building.
All sleeved Iron refits come with Iron Retexture's cubemaps set-up by default.
If you're building the pants-on Tullius refit, make sure Imperial Armors and Weapons Retexture SE - Penitus Pants.esp is active in your load order, or else texture swapping will break for the Penitus Oculatus armor! This also goes for the HDT-SMP sleeved Imperial Light refit and Imperial Armors and Weapons Retexture SE - AmidianAddon.esp if you're using AMB Content Addon as the Imperial Outcast texture swap will break otherwise.

Be sure to pick the same Morokei color you've chosen from Dragon Priests Retexture in AotDC's FOMOD! All AotDC BodySlides are contained under the HIMBO Armory of the Dragon Cult category, separate from the sleeved armors for building.
