Generally, because the neckline of the old cheongsam is relatively wide, it is necessary to choose a pearl necklace that is slightly longer than usual, otherwise it will be tight. If you wear a short pearl necklace, it is generally about 48-52 cm. If you wear it for a long time, it is generally recommended to be about 80-90 cm. Of course, you can also go around 1 twice, so you can choose 140 cm.

I hope I can help you and adopt it. Thank you!
