Washing was to no avail, so I scraped off some with a scissors blade, then we covered it with black permanent marker. Luckily, the smear is not right on the front of the sleeve. I don't think it shows enough to be noticed now, but oh, my equilibrium! I feel like cursing and crying. Instead, I will get some coffee and do a little research before I go to the interview. Oh, and try to get some of my actual current job work done.
I hope I can turpentine the stain off later. This is a very useful dress.
I am grateful I wasn't wearing my $300 jacket at the time.
