The engagement ring—and the couple’s wedding bands—are all from Taffin, the bespoke jewelry brand by James de Givenchy, Sean’s uncle. James’s signature is his colored ceramic bands, and Sean chose the light blue color for the engagement ring with a pear-shaped diamond. “I think it is a true reflection of my personal style,” Dahye says. “And I always get so many compliments on the uniqueness of the colored band.”

The wedding was held at the end of the summer in Paris, where Sean’s mother and brother currently live. Sean spent much of his upbringing in France, and given the couple celebrated their civil union in New York, it felt appropriate to have their church wedding in the groom’s home country.

They had three days of celebrations from August 28 to 30, starting with the rehearsal dinner for immediate family and the wedding party, then a welcome brunch for younger family members and friends to meet, and finally the wedding ceremony and reception. “I am so glad we were able to stretch out the events as it gave us time to genuinely connect and converse with family and friends who we haven’t seen in a while,” Sean says.

When the couple began planning, Dahye was in her master’s program, and Sean was working full-time, so they didn’t have much free time. “I think the hardest part was getting the ball rolling,” Sean remembers. “The good thing was that we had a full year and a half to plan following our civil union in New York City, so not having the stress of time pressure certainly helped a lot.”

They enlisted Marie Bitton from Maiden Agency as their planner, and the first thing they did was lock down a date with the main venue, Le Pavillon Dauphine. It checked off all the boxes: grand and historical architecture, a vast outdoor space, and just far enough from residential areas so that there was no risk of noise complaints. “My vision for the wedding was timeless, classic and undoubtedly Parisian,” Dahye says. “I am a big vision-board nerd, so I spent many a weekend finding images that show the vibe and inspiration for each event. Once I was happy with this vision board—which was a PowerPoint deck of 100-plus slides—I shared it with Marie, and she did her magic to scout the right vendors and designers from there.”
