It's interesting to see that people on both ends of the spectrum of reasons care about this;

- People who are focused on the mechanics and who think about sale value, and carry weight, give those things as the reasons - they don't want to lug around anything that doesn't serve a purpose, and in the game, clothing doesn't unless it's enchanted. For them, they're going to be seeing their characters in their underwear if they're unarmoured characters, so they want them to look visually satisfying, or to have options for that reason.

- At the other end, you have folks who are mostly focused on character roleplaying, and immersion in the world and in the character that they're dropping in to; they want to have undergarments that they feel make sense for their character to wear, or the ability to choose an option that suites them, on purely character aesthetic grounds.

And then there are folks all along this spectrum, somewhere in between, who feel both reasons to varying degrees in minor or major ways.

(Of course, there are also those who want to their characters to look sexy in their underthings for eye-candy reasons, too, and there's nothing wrong with that either)

It's an interesting observation, I think ^.^ Regardless of what direction you come at the desire from, more and better customisation options would not be a bad thing here - and giving us some variations is the first step in a right-ish direction, from what they were before. Now keep going, and give us more complete customisation, please.
