What would be the best gift for my wife on the 3rd anniversary of our wedding? She loves jewellery and dresses but I am thinking of gifting her something unique. Any recommendations are welcome.

My Daughter is getting married next to next month and till now she has not been able to decide upon the wedding gown. She is very moody and I think I am on the verge of giving up. How do I make her choose the perfect wedding gown?
