Daughter gets married without dowry.

Not necessarily, but the man's wife must have more material, financial and so on. More than women. It is also polite if the woman's family can accompany some dowry. There is no contempt, so it can be said to respect the man as much as possible, but it can also be explained according to the conditions. If the conditions at home are quite poor, you can send some practical ones, not too fancy.
