The one who should be nervous when the prospective son-in-law comes to visit should be him. Marrying your daughter to him is the best gift, so he will be happy even if it is a simple little gift.
First, since he is your prospective son-in-law, you can give him and your daughter a pair of couple rings, hoping that they can hold hands for a lifetime. I recommend you a simple platinum ring that young people like. It is not only fashionable and trendy, but also can be engraved for free, which has a certain commemorative significance for them.
Second, watches are one of the main accessories for men. An exquisite and high-end watch can highlight their taste and temperament, so a stylishly designed and high-quality mechanical watch will be a very good gift. With this meeting gift, the prospective son-in-law will definitely be filial to you in the future.
The prospective son-in-law should be a white-collar worker working in the workplace at this age. The image of the workplace has a great influence on the development of young people. You can choose a delicate tie clip for him, match it with professional clothes, and let the son-in-law meet the challenges of every day with extraordinary vitality.
