Kate Bosworth wasn't the only stylish bride coming down the aisle this weekend. In Monaco on Saturday, Tatiana Santo Domingo said "I do" to Andrea Casiraghi. The well-connected couple — she's the niece of Lauren Santo Domingo and he's the son of Caroline of Hanover — wed in front of chic guests including Karl Lagerfeld, Eugenie Niarchos, and jewelry designer Noor Fares. The bride wore a plunging custom Missoni embroidered gown and a boho baby's breath wreath to match the dress's laid-back tone. While we only have a singular official shot to muse over, Instagram has gifted us with a virtual wedding album to peruse.
