Jennifer Aniston shunned tradition and opted for a boho-inspired, flowing summer dress for her wedding to longtime love Justin Theroux. The A-list couple tied the knot at a surprise ceremony at their Bell Air mansion Wednesday. According to insiders, Jen’s wedding-day look was laid-back and relaxed. 

“It was very simple, but beautiful. It wasn’t a white color -- it was like an off-white, cream color,” a source said. The insider added the dress was “very classy, fitted well and simple.” The bride shunned the usual lavish designer gown for a summery number, which was easy to dance in, the source added.

Versace, Gucci and Vivienne Westwood’s reps confirmed they did not design Aniston’s wedding dress. Saint Laurent gave a cryptic “No comment,” to WWD. The “Friends” actress is a huge fan of the label, especially the minis. She’s also turned to the designers at Valentino for a variety of her major red-carpet appearances.

Aniston spent a whopping $50,000 on a Lawrence Steele gown in 2000 to exchange vows with her first husband, Brad Pitt, the Mirror UK reported. But her style sense has leaned more European in recent red-carpet appearances. Aniston wore Versace for this year’s Oscars.

Aniston’s trusted glam squad and close friends -- celebrity makeup artist Angela Levin and go-to hairstylist Chris McMillan -- were on hand to get her ready and celebrate the occasion. The couple’s close friend Jennifer Meyer designed their wedding rings, a rep for the celeb-fave jeweler confirmed.

The couple kept their big day under wraps and guests were told they would be celebrating Justin’s 44th birthday. The ruse worked so well that some guests, who thought they were going to a barbecue, apparently even showed up in jeans.

Courteney Cox, the actress’ BFF and "Friends" co-star, acted as the maid of honor at her wedding. While no details of a bachelorette party have leaked, Theroux is understood to have waved goodbye to his single days with a party at chat show host Jimmy Kimmel’s mansion.

Aniston and Theroux were spotted catching a private jet out of Los Angeles heading to Bora Bora for their honeymoon Thursday. Aniston even got her BFF Cox to her honeymoon.
