Jennifer Aniston is beginning to narrow down the list of designers she may ask to make the dress she'll wear to marry Justin Theroux.

For now, the name at the top of the list is Victoria Beckham, according to the United Kingdom's Now Magazine.

"Jen's a big fan of Posh's fashion range, and she's one of the names being considered, along with Valentino and Carolina Herrera," an insider told the magazine.

Look magazine reported that Aniston wants to keep her bridal style from getting too extravagant, and she'll likely opt for something form-fitting that shows off her physique. 

Beckham's simple aesthetic is a perfect match for what Aniston wants in a bridal designer, according to Now.

"Jen wants a dress that's simple and classy, which is what Victoria's known for," the source said.

Aniston wouldn't be the only one to benefit from the wedding day collaboration. Beckham 's profile as a fashion designer would be raised immensely if Aniston wore her work on the actress' big day.

"Even by Victoria's standards, it would be a huge coup as Jen's wedding will be Hollywood's biggest event in years," a friend said. "It would cement Victoria's place at the very top of the fashion elite."

Aniston is getting ready for her nuptials in other ways as well. Reports claim she has decided not to sign a prenuptial agreement with Theroux. Despite the advice of her business managers, Aniston doesn't feel she needs to protect her reported $150 million fortune from Theroux.
