I attended a viewing this evening of a close family friend, and since I didn't go home to change, attended it wearing what I wore to work, which was jeans. Nearly everyone was dressed up except for me. I didn't think was of it until a met up with a friend afterwards, who told me nicely that I was inappropriately dressed. I'm guessing since everyone else was dressed up that I made a faux pas, but was it a terrible one? I was truly fond of the deceased, who himself had been a casual guy, and I doubt his family would have been offended, but now I feel self-conscious.
