1. If you have a good relationship with your wife and your classmate has a good relationship with his other half, it is no problem to take your wife to the wedding, which can also reflect your blessing and respect for your classmate's wedding.

But if your wife is not familiar with your classmates, or you don't want your wife to be the focus of attention that day, it may be more appropriate not to bring your wife to attend.

In short, with or without a wife, a gift and blessing are essential. This is not only a respect and blessing to the newlyweds, but also a treasure of friendship and affection.
