Well, I think I just managed to ruin my shirt today.
It's light blue, and I was making coffee for my fellow coworkers (I don't drink coffee, I was being kind) and I managed to spill a bunch of hot coffee on my sleeve.
I'm ok, but the coffee dried quickly. I did manage to get some spot remover on it, but I'm not sure I was quick enough. I can wear it with sleeves rolled up, but otherwise, I think this shirt is pretty much garbage now.
