I messed up. Serious dad move.

Ok y'all I need serious help. I really really messed up my 2yo favorite dress by putting blue pants with a pink dress in the wash. I really thought it was on for cold and wouldn't be a problem, but I'm a dodo and it ....wasn't. now the dress is a gross purple thing and splotchy. . (And my wife will rightfully kill me).

How can I get the blue dye out of the pink cotton and tulle dress?

Thank you for saving my 🥓🥓🥓
