Remember what happened in the fashion world back in April 2023? Of course you do. It's when Sofia Richie married Elliot Grainge in the so-called royal wedding of the year. Held at the Hotel du Cap-Eden-Roc in Antibes, France, the festivities drew worldwide attention. Now, a little more than two years later, Sofia and Elliot are back in Europe—except this time as wedding guests.

In Monte Carlo, Monaco, the couple attended the nuptials of Charlotte Bickley and Charlie Meller. For the black-tie soirée, Sofia wore a striking Schiaparelli blue gown with a halter neckline. I personally avoid wearing strapless dresses to weddings because they're prone to sliding down on the dance floor, and now Sofia's choice has further convinced me to sideline the silhouette. A halter dress is equal parts elegant and practical, so it's really a no-brainer for weddings this summer. Scroll down to see Sofia Richie Grainge's wedding guest look in Monaco and shop similar dresses.

Erin got her start as a Who What Wear intern over 14 years ago—back when the site only published a single story per day. (Who What Wear has since increased that number twentyfold.) She graduated magna cum laude from USC, which is how she ended up moving to Los Angeles from her hometown of San Diego. In college, she also interned at Refinery29, where she was promoted to editorial assistant and then assistant editor. After nearly three years at R29, she came back to WWW in 2015, where she currently holds the title of Associate Director of Fashion News (as well as the unofficial title of resident royal expert—in case you haven't noticed her numerous Kate and Meghan stories). She spends her days trying to incorporate her idols, Anna Wintour and Roger Federer, into as many stories as possible.
