The worst thing to ever happen to James Costello was also the best.
The Boston Marathon bombing survivor – who was famously photographed in the wake of the April 15 attack
, burned and with his clothes hanging in tatters – has married Krista D'Agostino, the nurse he met in rehab
after the tragedy.
The couple celebrated their union on Saturday at the Hyatt Regency in Boston, where they "danced the night away," Emily Sharp, a rep for the hotel, told the New York Post
“It was an elegant, Nantucket type of theme, which is one of the couple's favorite places, a nod to their cherished memories together, a real fairytale vision,” Sharp added. "It was just so much fun."
Wedding planner Rachael Gross told The Boston Globe
that the pair, who chose John Legend's "All of Me" as the song for their first dance, went for a nautical theme, "but without the literal nautical elements."
"It was such a true representation of their character, their style and their love," shared Gross. "Everyone was soaring, soaring."
Sam Adams Brewery donated a special "Brewlywed Ale" to the event, which included about 150 guests.
Costello, 31, proposed to D'Agostino
, also 31, eight months after meeting her at Spaulding Rehabilitation Hospital, where he was transferred after undergoing multiple surgeries at Massachusetts General Hospital following the attack.
"April 15 was one of the worst days of my life. I soon wondered why and for what reason this has happened," he wrote in a Facebook post in December. "I now realize why I was involved in the tragedy. It was to meet my best friend, and the love of my life."
