Pippa Middleton's Giles Deacon wedding dress makes bridal fashion history

It's official! Eccentric British designer Giles Deacon was the Duchess of Cambridge's younger sibling's choice of bridal designer for her-high society nuptials with James Matthews.

Deacon had been spotted in November, taking clothing bags into Pippa Middleton's home, sparking rumors of a high profile appointment.

Her bridal look was equal parts prim and fashionista: the Victorian-style wedding dress featured a demure high-neckline, edgy cap sleeves and an on-trend cut-out-detail at the back.

In a nod to tradition, the bride complemented her all over lace-corseted gown in radiant white with a tulle-filled train and cathedral-length pearl-studded veil by the Middleton family's go-to milliner Stephen Jones.

Style lovers and "Sex and the City" fans will be pleased to note that the bride wore Manolos.

Pippa clearly had an impossible act to follow after her sister's fairytale wedding to Prince William six years ago, and yet Mrs Matthews' bridal attire has been widely met with critical acclaim.

British Vogue was among the first to post an 'instaglam' photo of the bride online, commending Pippa on her "beautifully old-school, classically chic number."

Similar enthusiastic style commentary ensued with London's Daily Telegraph deeming the bridal gown "classically beautiful." "Like her sister's, a spin on tradition" was Harpers Bazaar's verdict, adding "she (Pippa) looked perfect."

"It's a privilege to show the craftsmanship that my team produces in London and a real testament to Pippa's support of British fashion," Giles Deacon told the Daily Telegraph, complimenting Pippa on her "great eye" for fashion.

Perhaps in anticipation of the post-wedding effect on his A-list client list, the designer announced plans to put his ready-to-wear line on hold in favor of developing the bespoke end of his business.

Much like the Duchess of Cambridge who wed in Alexander McQueen, Pippa is a faithful supporter of Britain's fashion talent.

The newlywed's wardrobe includes British luxe labels Emilia Wickstead, Alexander McQueen, Alice Temperley, Suzannah and Tabitha Webb and more accessible high-street names such as L.K. Bennett, Topshop and Whistles.
