At the son's unlocking ceremony, the mother can wear clothes suitable for the season. It is generally recommended to choose evening dresses with darker colors, such as blue, green, red and purple, which can highlight the mother's sense of maturity and dignity. In terms of style, it is recommended to choose a slim evening dress, not too young or eye-catching style, and try to be conservative. Solid color dresses and elegantly tailored skirts are better choices. If mom likes to add some small details to the dress, she can choose a dress with flowers, lace, beads, hollowing out and other small details, which can not only add elegance, but also show the charm of women. It should be noted that in the unlocking ceremony, there is a link in which the mother should stand beside the child with a towel and kowtow with the child. Therefore, it is suggested that mother should consider this link when dressing up, and try not to choose too complicated hairstyle or headdress, so as not to affect the ceremony.
