Grits: I like the Royal Vamp outfit best of the vamp gear. The cape gives it a neat touch. The thing I do not like about all the vamp armors is how they leave the top of your chest bare. Though granted, the vanilla hide, studded, and fur armors are much worse!
*imagines sweat trickling down Niv's cleavage* Are you sure Niv would not want that? I can think of some situations where that would be really nice.

The blood OTOH, I could definitely do without.
Joking aside, Aja is a crossbowwoman first. But she still gets into the thick of things with sword and shield as well. So something that actually looks like armor would be nice.
Diadem of the Savant is over in the Rift right? Just outside of that hunter's shack in the mountains, with the kid who survived Helgen? Amaterasu tried that on once, but did not like how it looked.
Acadian: I like that red and white outfit best as well. The trouble is it
this hole in her chest, just under the neck. I never noticed it before, but it was in Neith's pics too. From some angles you cannot see it. But now that I know its there, its all I can think of.
King Coin: I never liked how the ruins of the gates always stay behind too. That is why most of my characters do not do the main quest. Well one reason at least.
I never noticed a gap under the belt on the Crimson Ranger Armor. It is the first mod the creator ever made, which is probably why. It is too bad, because the rest of the armor is outstanding, one of the best I have ever seen.
Now you have given me the idea of playing a princess with another character. That would give me a good reason to use the Eisen Platte. It is just too hard for me to justify a character wearing it. In Oblivion the more outlandish armors do not seem that out of place. But in Skyrim they really do seem too strange to me. I think OB just has a more superheroish feel to me.
I never tried the original Triss outfit. I think its colors look really good on AjaAs KC said before, everyone looks good in Elven Armor. But I also really like how the cloth pieces complement Aja's hair and skin.It has come down to these two. I love the look of the original Triss, but it does not look very armory. It is more of an outfit for a squishy mage type. The Elven looks good, but with Aja being a Redguard from Hammerfell that seems like an Israeli wearing an SS uniform. Then again, Hannibal outfitted his army with captured Roman armor and weapons after Cannae. And the Romans of course stole most of their best armor and weapon ideas from their neighbors in the first place. Maybe it is a family heirloom, won by Aja's mother in the Great War? I like that idea.
All of this really illustrates what kind of a gamer I am. I sit and agonize for days over what to wear, rather than my character's stats!
