Bodies

I use CBBE and HIMBO (nevernude) to customize bodies a bit, though I definitely stay fairly Vanilla. NSFW pics in below links.

For men, I like The Common Guy.

For women, I use my own Vanillaesque preset which I like to pair with this mod Female Hands Redone

Honorable Mentions:

Almost Vanilla - Himbo

REACHbody CBBE

Realistic Body Presets CBBE

Retextures

Skin

I pick Tempered Skins for the fellas mostly because it has an option for a 'Sleek' body diffuse: meaning, you can actually have a texture that doesn't have an 8-pack. My main complaints are that it can wash out some skin colors and the ears look pretty bad (then again, I haven't seen any skin mod that fixes this.)

For the ladies, Reverie is genuinely my favorite texture out there. I like the option for adding body hair (including arms, armpits and legs!) because most ladies in Skyrim aren't gonna bother with shaving every day. Works great with all skin tones.

Mild Complexions

What it says on the tin, makes complexions slightly less extreme.

Hair

Sassy Salt and Wind Hair Retexture

Self-plug here, my attempt at making Salt and Wind a little more gritty. Covers both Vanilla and KS Hairdos. I also use my hair recolor addon, and my Beards recolor, otherwise colors look a little off IMO.

SC - Vanilla Hair Retex (Tiled Textures only)

I just use the tiled textures from SC's, which are mostly used for Redguard and some Orc hairs. My normal edits make them a lot less shiny than the original.

Eyes

Fia's Eyes

I really like the style of these eyes, though I did replace the eyelashes in my own game. Really offers nice variety while keeping the racial variations in scalera and pupils.

ESO-Style Bosmer Eyes

My own addon, gives Bosmer eyes the star-shaped pupils they have in ESO.

Teeth

Setup for simple, natural, 2D teeth (I think 3D is way overkill.)

Miggyluv's Natural Teeth (Simple Teeth Overhaul)

Orcodontist

Miggyluv's Natural Orc Teeth (for Orcodontist)

Meshes

High Poly Heads (EFM version)

I highly recommend installing the original Expressive Facegen Morphs and both Expressive Facial Animation (Male and Female) mods and letting HPH overwrite them. Also, this fix for male eyebrows.

Closed Mouths for Orcs

Covers orcs' bottom teeth (minus the tusks of course), a must-have. Gonna try it out with Alternate High Poly Head eventually.

Vanilla Hair Remake (non-SMP)

Admittedly, I use a highly edited version of this mod, one that I've taken the braids from High Poly Vanilla Hair and replace VHR's braids with.

HammerHair

A hearty selection of hairs for Redguards (finally!)

Orc Brow Horns

Another of my mods, removes the green tint from Orc's brows horns (optionally adds them as scars for mixing and matching and more.)

Cuyi's Bosmeri Antlers

Love these to pieces, a must for Bosmer players.

Brows

LM's Eyebrows (Standalone)

LM's Dual Brows (Standalone)

Blackmoon Brows

LDD - Detailed Eyebrows for HPH

Plus my own edits for Male brows

Khajiit

Khajiit Overhaul (Plantigrade version)

The high poly heads included with KO are a LOT nicer than HPH's, IMO. That being said, the male head is a little wonky, so I use this preset as a base. katie and vaharadaro have some excellent presets for KO.

Khajiit Character Creation Extended

More RaceMenu sliders for your Khajiit.

Khajiit Male Lion Textures

Lioness Look

I pair the diffuses from these mods with the normals from CoverKhajiits. I personally like the cleaner look of lion textures, as they let the warpaint/overlays show up clearly. CoverKhajiit's normalmaps have a nice furry look to them.

ESO-Inspired Eartufts

Khajiit Ear Fluff

3D Khajiit Brows

Argonians

The Argonian equivalent of K.C.C.E.
