Kate Bosworth wore an Oscar De La Renta bridal gown for her wedding to Michael Polish.

The 'Superman Returns' actress wed her film director beau in an intimate ceremony for 50 to 70 friends in Montana on Sunday (31.08.13), and the blushing bride stayed true to her fashionable reputation by sporting not one, but two custom gowns by the famed fashion designer, according to Martha Stewart Weddings, which helped organise her big day.

Kate was adorned in a simplistic strapless ivory ball gown - featuring an eight-foot long, 16-foot wide train - for the nuptials. However, she later changed into a chic floral print tulle dress with an illusion neckline and scalloped cap sleeves for the reception.

The stunning 30-year-old beauty teamed her gowns with equally glamorous ivory-coloured Jimmy Choo sling back heels, which are encrusted with crystals across the front strap.

Meanwhile, the groom wore a dapper three-piece charcoal suit from Brooks Brothers.

Kate is known for her stylish sartorial choices, often being named to best dressed lists, and she has even landed her own fashion line with British high street chain Topshop after fronting a campaign for the brand last year.

The actress previously listed Stella McCartney, Alexander McQueen and Christopher Kane among her favourite British designers.
