How-Not-To: Make a t-shirt soft

About two months ago I got a t-shirt from Buffalo Exchange in Brooklyn. It is an XL regular-fitting black short sleeve t, with Ziggy Stardust plastered across the front in neon ink. I loved the idea of the shirt, but didn't necessarily love the shirt, because I could tell it was going to be boxy and stiff. I bought it, nonetheless, and I think it was an OK deal for $9. I've worn it a couple times, but really didn't feel comfortable with the fit of it. So, I decided a would make use of my time at home, and brought it back with me. I googled everything from "making t-shirts soft" to "which chemicals can I use to break down fabric." I found a couple of suggestions online. Most sources told me to go to town to it with a cheese grater, rub it with sandpaper, etc. However, I was looking for an easier option, such as soaking the shirt in some magic solution to make it look like it had weathered ages of wear and tear. The only option like this that I read was to soak the shirt in vinegar and salt. So, soaking the shirt in vinegar and salt is what I did. For two days. Fail. Doing this only made my house smell like rotten eggs. Luckily, the smell didn't stay with it when I washed it, so I'm back at the beginning.

1. Vinegar is not the miracle solution that most home magazines make it seem. At least to me.                                                                      

2. An industrial-strength, XL, sander, with unlimited amounts of sandpaper, would be appreciated.

I will continue my search for the perfect, DIY, solution to make the softest, thinnest, most comfortable fabric.

Note: I just found out that there was a Buffalo Exchange in Manhattan. Right near me. Not sure if this is good or bad.
