Hmm, I think it's inappropriate, I don't understand why people do things like this. Different opinions of acceptable behavior I guess. I would not like this either.

However I don't think it's the gnarly mess or as someone said cellulite that is the problem. That's kinda like saying only beautiful people should be seen.

At work tho, not really appropriate. I might do that with my sister or friend, but I wouldn't lift my shirt and ask about my pant fit with my boss, I am sure he/she could have asked someone else, someone closer.
