Plastic underwear, my friend who is getting married also has a small belly and a big belly. In order to put on a wedding dress and have a good figure, she bought plastic underwear on Taobao. She said the quality was not bad. Taobao's plastic underwear store seems to be called "Baodi Gege". I went in to have a look that day. There are many well-known brands of high-end plastic underwear, such as Mark Baodi, Tregoni, Age-less Myth, McNisha and so on. You can go and have a look.
