Just married! Colombian heiress Tatiana Santo Domingo pictured with her new husband, Prince Andrea Casiraghi, after their wedding on Saturday in Monte Carlo
Boho style: The bride wore a Missoni gown with her hair worn loose and a garland of flowers on her head
'The dress also featured a full-length circle skirt with a macramé effect supported by two layers of silk organza which charmingly matched her five-month-old son Sasha's bloomers,' the magazine's website reported.
She teamed her gown with flat silver sandals and wore her hair loose with a garland of flowers on her head.
The couple, who have been together for seven years and have five-month-old son Sasha together, were greeted by cheers as they left the Prince's Palace after the late morning ceremony.

Among the 400 guests present at a lunch afterwards was the cream of Monaco society. The principality's reigning monarch Prince Albert, his wife Princess Charlene and his sister and mother-of-the-groom Princess Caroline were all in attendance.
Charlotte Casiraghi, the bride's sister who is believed to be around six moths' pregnant with fiance Gad Elmaleh, and apparently introduced the happy couple, looked elegant in pale blue.
Also in attendance was Karl Lagerfeld, the Missoni family (minus Margherita who is due to welcome her first child any day now), Greek shipping heiress Eugenie Niarchos and the bride's aunt, Lauren Santo Domingo.

Later, for the evening celebration, Tatiana appeared to have changed into a different creation by the Italian family-owned fashion house, with longer sleeves and a different style of lace embellishment. She removed her floral headdress and instead accessorised with a pearl-embellished clutch.
The build-up to the royal wedding was documented last week by Lauren Santo Domingo, who shared a snap of Tatiana's bachelorette aboard a luxury yacht.
The photo on Instagram showed the ladies all dressed in white lace ensembles and floral headbands, with picturesque mountains in the background.
In contrast to her guests, the bride-to-be stood out in a red dip-dye dress and matching red lipstick, and her photogenic pooch sitting on her lap.

Tatiana, a regular on the New York social scene, dated Andrea for seven years before they announced their engagement in July 2012.
In March 2013, they welcomed their first child, a baby boy named Sacha, who is third in line to the Monegasque throne.
A spokesperson for the couple has said their August 31 wedding would be a 'private affair', but many believe she will follow in the footsteps of Lauren, whose 2008 wedding was highly publicised and featured in a ten-page spread in Vogue.
Tatiana is the daughter of Colombian businessman Julio Mario Santo Domingo, Jr, and Brazilian socialite Vera Rechulski.
Her late grandfather, Julio Mario Santo Domingo, was thought to be worth around £5.5billion.

In 2009, she started a fashion line, Muzungu Sisters, with her friend Dana Alikhani, who was also pictured on the yacht, and she was included in Vanity Fair's 2010 international best dressed list.
Other guests on the boat included Tatiana's future sister-in-law Charlotte Casiraghi, who flattered her baby bump in a long white dress with crochet details on the hem.
Andrea Casiraghi, who is second in line to the throne, is the grandson of Grace Kelly and son of Princess Caroline and the late Stefano Casiraghi.
This weekend's wedding is the first of two to take place this year within the royal family of Monaco.
