I’m also in team gold and white. Just like you, my brain perceived the source of light is from the back and part of the dress that I saw is shaded.
What helped me see the dress as black and blue is trying to imagine a zoomed out image of this photo where the dress in uncropped, then force myself to believe that it is a brightly lit clothing shop. Also I tried to see the background as a mirror that reflect the light, so my brain can finally process that the lighting is not exclusively from behind the dress.

You just made me manage to see it in black and blue! Wow! Never spent too much time on it but always saw it gold+white.
