What's a good rich person weapon/armor set?

Try Ulfric's Clothes (comes with some amount of armor), Glass Dagger, and a Cirlet. See how that looks.

There are some really neat clothing mods, especially the cape ones. Check some out on the Nexus.

It'd be cool to have Ulfric's clothes on normal days, and Tulius' clothes for riding into battle.

Why is this in the roleplaying forum?

The thread is about roleplaying isn't it 

"For role-playing purposes" ~the OP of this thread

thats why.

Oh sorry, check out the nexus mods threw me

Search 'Noble Clothes'

It's a recolour of the garb Titus Mede 11, and several jarls wear.

The Emperor Robes could also be a good choice.

The robes and dresses the Jarls were are quite nice. 

If you wouldn't mind a bit of commands, Fine Raiment or Embroidered Garments are nice. As for a weapon, I'd say a glass sword.

'Tis The above guest here again.

I suggest Nightinggale Sword.

Nice, detailed sword with an actual hilt.

Gloves and Fine Boots complete the package.

Gilded Wristguards and Fine Armguards would be cool

Also, the Thalmor Mage's clothes look pretty regal to me. Once again with the Nightingale sword, because of it's sheath and tecture.

Blades armor. 

Royal vampire armor, ancient falmer boots and gauntlets, and a dawnguard full helmet. And the nightingale sword.

The elven sword or greatsword, they are gold and look pretty fancy. As for amor, giled wrist guards snow elf armor and boots and a circlet

im using the sand colored Dunmer outfit, hevnoraak dragon mask, steel plate gauntlets, vampire boots, and a moded 2 handed katana on my back. it isent a powerfull armor but ime doing oka on expert and it has that Traveler look to it that i realy like. try it out guys

Radiant Raiment Fine Clothes look pretty fancy and you can get them by showing them to Elisif the Fair for Taarie.

Nightingale Full set (Sword, Bow, Hood, Armor, Gauntlets, and Boots) you can get additional armor bonus (if you don't trust me, wear it and see your active effects)

This is a very old thread, 97.90.194.178 was on PC so like Sky Above,Voice Within said mods (and capes).
