Remove the black stripes from the end of the sleeves on the default model

The black stripes at the end of the default t-shirt sleeves look really bad when colored anything but black.
I think it would make more sense to have them change color with the rest of the shirt.

At the very least the color could be less harsh, maybe a very dark grey instead of void black.

Also, I feel like the t-shirt model should be an outfit choice instead of having to switch back and forth between characters to wear it. I just didn’t think it’d worth making another forum post about it.
