Yesterday I watched a video about a new version of strapless bra released in Japan. If you have time, you can buy it and give it a try. Although I'm not sure if it works well, I've been thinking about it for a long time. If you wear it for dancing for too long, it may cause tofu to sag. Anyway, try to buy it and give it a try. If it doesn't work well, you can give it to me to explore and see if there is still room for upgrading
