Anna Wintour smiles arriving at Serena Williams’ wedding

Anna Wintour’s iconic fringed bob looked pristine when she was glimpsed in a car arriving at Serena Williams’ swank wedding festivities on Thursday.

Serena is tying the knot in New Orleans to Snapchat co-founder Alexis Ohanian, by whom she has a two-month-old daughter also called Alexis.

Wrapped in a colorful, tight print dress, Anna, 68, who has reigned as editor-in-chief of American Vogue since 1988, was of course in sunglasses.

Anna’s penchant for wearing shades is such that she’s frequently seen in them while sitting front row at indoor fashion shows.

On 60 Minutes, she dished: ‘Well, they’re seriously useful. I mean, I can sit in a show and if I’m bored out of my mind, nobody will notice, and if I’m enjoying it, nobody will notice. So, I think at this point they’ve become, really, armor.’

When seen on Thursday, Dame Anna had opted for a pair of black-rimmed purple sunglasses, complementing the purple accents on her dress.

Wineglass in hand, Anna was spotted balancing on a pair of stilettos as she mingled with the other guests during an alfresco portion of the days’ revelry.

Her form-fitted half-sleeved dress emphasized Anna’s reliably svelte frame.

Anna has had two goes at marriage, first from 1984 until 1999 to child psychiatrist David Shaffer. They have a son, Charlie, and daughter, Bee, both in their 30s.

In 2004, Anna married her current husband, Texas-born businessman Shelby Bryan.

Should Anna elect to give Serena any marital advice, fidelity may not be quite her area of expertise – Anna and Shelby infamously began their relationship while both of them were still with their first spouses, per New York magazine.

Meanwhile, Thursday’s bride has long found a friend in Anna – whose father Charles once edited the London Evening Standard and had a glacial persona of his own, earning him the handle ‘Chilly Charlie,’ as Anna conceded on 60 Minutes.

Around when she released clothing collection, Serena told the New York Post in 2015: ‘Anna’s really been my mentor. She’s gone over this whole collection.’

Earlier that year, Serena had covered American Vogue, with the coverline beside her photo trumpeting her as ‘QUEEN SERENA.’
