Input: This morning, I was in my building's laundry room doing my laundry before classes, and I hadn't showered yet so I was wearing a tea shirt and sweat pants. While I was putting my clothes into the washer an old lady told me that I should be more respectful and not wear sweat pants and "such a ratty shirt" when I'm outside my apartment. I told her that I'm just coming up to do my laundry and I'll change after I shower, and she tells me that I need to "have some respect for the world" and dress nicely whenever I am outside. At this point I am expecting that she just wants to bitch me out and I don't really want to have a conversation about it so I just say "no thanks" and pretend I can't hear her while she keeps lecturing me and complaining about me to other people coming in and out of the laundry room, and she even follows me down the hall to the elevators (though luckily not into the elevator with me).

Was I being an asshole here or is there no other better way to handle this? Also I have no idea if it is really wrong to wear a tea shirt and sweat pants in my building, as far as I know we don't have a dress code and it's not like they have holes in them or stains or anything.
