My previous comments and a previous discussion...
Although it's true that everything was new at one time, when recreating a persona, I like to offer an image of someone who has been around for a while. Nobody had all new gear at once, except in the movies.
I prefer my stuff to look like it's "been used before today". Otherwise, if all my clothing and gear were new looking, it might appear that I just dressed up for a photo, rather then someone who actually participates.
Remember all the TV westerns in the 50's where everyone had on brand new clothes from the costume department?
When I talk about wanting my stuff to look used, I'm talking about subtle degrees. I do age knife blades slightly, so they aren't shiny, but I would never artificially age my leggings or moccasins, etc., as they get pretty used looking on their own in a very short time. I also don't want my gear to look two hundred years old, as that would be implausible. My stuff should look like it is being used "at the time" by my persona, not like a 200 year-old piece that a collector would have in their collection today.
I tend to use the term, "broken in", rather than aged.
