Many people can't wear cheongsam. I wonder if you have checked your arm. Many cheongsam designs are sleeveless. If you put on a cheongsam and just show your unicorn arm, you will know that the effect is really terrible.
Girls can see if their arms worship meat first. If they do, even if you are slim, it will affect the effect of wearing cheongsam. In addition, the sleeves of cheongsam are generally designed to fit closely, so it will be very uncomfortable to wear cheongsam with thick arms. It will be painful to wear it all day.
