Taylor Swift's Wedding Dress at Margaret Qualley's Wedding 

Taylor Swift has garnered the ire of social media users for her choice of wedding attire for Margaret Qualley and Jack Antonoff.

Antonoff, 39, and actress Qualley, 28, married on August 19 in New Jersey, just over a year after they got engaged.

Swift has worked closely with Antonoff on several of her albums and was one of several A-list guests for the wedding. 

 Other notable attendees were Zoe Kravitz and Channing Tatum, as well as Cara Delevingne and Lana Del Rey.

Andie McDowell, Qualley's renowned mother, was also present.

The "Shake It Off" singer wore a lace midi-dress by London-based designer Erdem, which had a corset-inspired bodice and an asymmetric hem.

Many people thought the outfit was white, which is against social etiquette because white is usually designated for the bride.

"Who tf wears white to someone else's wedding?" one user commented on Swift's wedding Instagram image.
