How is the settlement of wedding trousseau handled in cases of separation without marriage?

In cases where a wedding ceremony was held but no marriage registration was filed,
and the couple decides to separate due to high stress from personality differences during cohabitation,
how is the wife's wedding trousseau typically settled?
1. She takes all the trousseau items, and no monetary compensation is provided.
2. She takes about half of the items, and the man pays her the remaining balance based on the price of new products.
3. The man pays her the full price of all trousseau items as if they were new products.
Which of these is the most common?
