Isabel Bailey's family doesn't know when she gave the dress away. One day, it was just gone.

Bailey lost her battle with cancer in 2009. In the weeks before her death, she gave away many of her possessions, including her wedding dress.

"She just had this mindset ... that there was no point in keeping a lot of her stuff," said Liz Bailey, Isabel's daughter.

Liz has gone online to search for the long-lost dress. She posted a Kiijiji listing on May 10 and shared the page with her Facebook friends.

The family suspects the dress was taken to a consignment store and purchased six years ago.

One distinguishing mark is a stain on the train of the dress.

"On her wedding night, someone spilled tea or coffee on the dress, so the stain was always there," said Liz.

Liz, her father and her grandmother are all hoping the dress will return to the family.

This renewed search was prompted by a Mother's Day conversation between Liz and her grandmother.

"I think she took it hard when my mom passed away. She had that whole mentality that parents should go before their children do," said Liz.

The dress is also an important link between her mother and widowed father.

"My parents were 10 days short of their 30-year anniversary when my mom passed away. It represents a good strong marriage and it represents my mom as a woman," said Liz.

She says she hopes anyone who thinks they may have purchased the dress from a consignment store contacts them.

Liz said she remembered "as a child, looking up at it thinking: 'I want to wear this when I get married.' It's such a beautiful dress."
