Wedding culture is constantly changing. Wedding hashtags are not as common anymore, wedding parties are often mixed-gender, couples frequently exchange their vows privately instead of at the altar and the days of out-of-the-blue proposals are long gone.

As planning a wedding continues to grow more expensive, and couples seek out new ways to personalize their nuptials, we wanted to hear from experts about what guests could expect to see at weddings in 2025, and what couples should keep in mind while planning.

From décor and fashion to food and officiants, these responses offer a glimpse at what the year may hold in store.

Rise of the QR Codes

In December 2023, Myka Meier went to a friend’s wedding near Boston. It was the first time Ms. Meier, the founder of Beaumont Etiquette, an etiquette consulting company in New York, saw a QR code at each table. The couple had set it up so that guests could upload photos that they captured throughout the event.

Though the couple confessed to Ms. Meier afterward that nobody used the code, perhaps because it was so new that they didn’t know what it was, Ms. Meier noticed the following year that a few of her clients had also generated QR codes for their weddings.

Ms. Meier said that she believed this trend would take off in 2025 — whether guests use it or not — because of its convenience. Guests who take photos and videos of the first dance, speeches and candid moments can upload them onto an album, and couples can easily view them all in one place.
