wedding bridal wears with 3/4 sleeves

Friends!! I need some advice asap! I bought a new shirt last night and wore it today. It had stained my arms, and some of my chest the color teal! I have an alterations appointment for my wedding dress at 4. Does anybody have any fast acting ways to get the dye off my skin?! TIA!! wedding bridal wears with 3/4 sleeves
