Margaret Qualley might not have been at Taylor Swift's wedding, but in 2023, Swift attended hers when she married Jack Antonoff, and some people are still talking about the color of the singer's dress. Granted, she didn't show up in white, but some believed the shade to be just light enough to look like it was. Oop! Those who paid attention to Qualley and Antonoff's wedding back then may recall that at the time, Swift's blue frock looked downright bridal in the wrong lighting.
