Jessica Alba is set to wear a $47,000 gown to her wedding party.

The 'Sin City' actress, who married Cash Warren in an intimate ceremony earlier this year, is planning a lavish belated celebration next month for her friends and family.

Jessica has also ordered a stunning custom-made off-white Chanel dress trimmed with lace for the bash.

A source said: "Jessica first wanted to wear a traditional gown with a veil, but then she changed her mind because she thought it would be over the top.

Jessica and Cash, who have a five-month-old daughter Honor together, tied the knot in a private civil ceremony at the Beverly Hills Courthouse in June.
