Dress falls very nice but was dirty and stinks extremely

When I opened the package, I thought I must be sick. The dress stinks extremely, I had to immediately hang onto the balcony. Then I saw that 2 black spots are indoors - I hope I can remove them. Otherwise the dress falls beautifully. But it is very thinly sliced, that is not to wear without a bra. I'm going to leave me by Schneider simply make upholstery pure, then it should be to wear for the holidays.
