I found this tutorial (video posted below) a couple years ago and started making my own shredded t-shirt. I finally finished it a couple months ago and wore it for the first time on Friday.
Note: It doesn't actually take years to make, I thought I was finished with it, but decided I wanted to shred it more. It got put on my to-do list and forgotten about. It's really easy, but take plenty of breaks and massage your hands.
Like I said, I wore this outfit on Friday and almost froze to death taking pictures outside. I probably would have worn my black cardigan over this, but I couldn't find it and didn't want to cover up this shirt. I love it so much that I kind of want to make another shirt! Anyway, I felt like a rockstar in this outfit, especially when I went out later and put my faux leather jacket on.
