With no photographs yet of Taylor Swift's much-discussed Dior wedding gown, the fashion spotlight has shifted to the guests and their carefully curated attire.

The singer's celebrity friends have been sharing glimpses of their looks on Instagram, offering the first visual clues from the highly private celebration.

As expected, the guest list delivered plenty of glamour.

Luxury fashion houses including Oscar De La Renta, Versace, Prada, Chanel and others dressed the star-studded crowd, with elegant gowns dominating the celebration.

Wedding etiquette typically dictates that guests should avoid overshadowing the bride. But this is Swift, arguably one of the world's biggest style icons, whose bridal look has become one of fashion's most anticipated reveals.

If anything, the polished guest wardrobes have only heightened expectations of what remains unseen.

Rumours surrounding the bride's dress have been circulating for weeks, before and after the ceremony.

According to a statement from her representative to People, the bride and groom's ceremony looks were created by Dior Haute Couture under the direction of Jonathan Anderson, the house's creative director for women's, men's and haute couture collections.

"This is the designer's first couture wedding dress for a world-renowned celebrity. Their shoes were custom made by Christian Louboutin and the bride wore Cartier jewellery," it read.

The secrecy has only fuelled further speculation.

Among the more extravagant rumours is the claim that the couture gown was so valuable it was given its own hotel room before the wedding.

Whether true or not, the story has added to the growing mystique surrounding a dress that, despite dominating fashion conversation, has yet to be seen.
