Jennifer Aniston is opting for a "simple" wedding style for her upcoming nuptials.

Friends of the actress have revealed what kind of bridal gown and wedding bands they think the she is likely to choose for her marriage to Justin Theroux.

Known for her toned figure, insiders are claiming that the stunning star is likely to chose a fitted wedding dress that highlights her fabulous body.

One of the bridal designers in the running is said to be Theia Bridal, a brand known for its fitted and elegant creations and whose mainline collection is worn by celebrities including Taylor Swift and Emmy Rossum.

Jennifer is also said to be favouring simple wedding bands.

With a $150,000 six-carat diamond and platinum engagement ring sitting on her finger, the down-to-earth star reportedly doesn't want to add a second big sparkler.

"Friends say Jen's likely to go for something simple by one of her jewellery designer pals like Jennifer Meyer or Anna Sheffield," British magazine Look reports.

Friends of the star also said the wedding will be the opposite of the extravagant ceremony she had with ex-husband Brad Pitt.

Several sources are tipping Jennifer to have a relaxed beach wedding in Cabo, Mexico, which is one of her favourite destinations and where she and fiancé Justin spent their first holiday.

"I would imagine [the wedding will be] tropical and small," her friend Kristin Hahn told the publication.
