The tennis star—who married Reddit co-founder, Alexis Ohanian, in a romantic Beauty and the Beast-themed affair in November—recently took to Instagram with never-before-seen photos from her dress fittings with Alexander McQueen creative director, Sarah Burton.
"When everything comes together for your wedding with a @alexandermcqueen Wedding gown by Sara Burton," Williams, 36, captioned the series of 'grams on Tuesday.
"Check out behind the scenes shots," the new mom continued. "I'm missing the fittings! Dream world My dear Sara Burton I love you so."
Williams's stunning one-of-a-kind dress is a strapless ball gown, featuring a full taffeta skirt and a bejeweled cape. The new photos, taken during a final fitting, show the beaming tennis pro modeling the bespoke number while designers work together on the finishing touches.
When it came time for the couple's star-studded New Orleans bash, Williams accessorized appropriately, with $3.5 million dollars worth of bling by XIV Karats.
We're still dreaming about your dress too, Serena!
