When the meat on it is covered, it will flow downwards. This may be because the corset you are wearing is not one-piece. I am wearing a one-piece corset from shoulder to thigh, which can shape the corresponding parts well. On the other hand, it may be that your size is wrong and you choose it too small, which will also lead to this.
At the beginning, it's best to wear it for an hour or two to get used to it, and then start wearing it for more time in a week or two, but not more than 8 hours.
Fat transfer is nonsense. Shaping, shaping clothes are used for shaping. The subject wants to lose weight to a great extent, and you need to keep fit for a long time, plus the shaping of the corset, in order to have a good figure.
I'm wearing it myself. Look at the picture.
