I'm not naming names, nor am I trying to dictate what other players should wear as they play the game since I know some people don't like to invest much money into SL, but I do have some pet peeves I thought would be best to address in the name of immersion and things generally making sense.

One would be clothes in general. The HUD tells players valuable information, such as the weather and temperature of the area, players don't seem to follow nor care of these given factors. It could be raining and terribly cold ICly and people are running around shirtless, in croptops and booty-shorts, and the other likes of revealing/minimal clothing. You would be terribly cold, why wouldn't you have warmer clothes to wear when it's raining cats and dogs or there's a present -20 wind chill?

My second gripe is one that should make sense, but I still see a lot of it regardless. High-heels. I don't care how long you've been wearing them or if you're faster than Usain Bolt, tripping, broken ankles, or the possibility of either to any reasonable person would have them leaving the heels at home or the bottom of the ocean. It's the apocalypse, surviving is a bit more important than that booty-pop.

These are just my personal gripes however and now I ask you. What about character attire or appearances drives you bonkers when it come to immersing yourself?

And try to refrain from naming names, as drama is no bueno for this Llama.
And I have no idea if this is the right forum branch for this kind of post, but fug it, I think it fits.
