In the blue bathroom, we see a not-so-subtle metaphor for Taylor's life, which has become a fishbowl for the media. Her lover (cough, Joe Alwyn IRL) willingly enters the fishbowl with her because he loves her.
What to wear: A flowy yellow or white cold-shoulder dress. It's also subtle, but remember that Taylor has yellow dip dye hair here as well!
