The function of shapewear is mainly to help women get rid of bad habits, improve and modify their body shape. Note that it is improvement, not change.
Therefore, you should choose the functional strength of the shapewear according to your own physical endurance, not the heavier the better.
Light or medium weight are more healthy and comfortable.
Although shapewear can make our body shape more NICE, but for health, you’d better not wear it for a long time. To maintain a better body shape for a long time, it is recommended that ladies develop good living habits through "fitness + reasonable diet". This is the healthiest and most lasting way to maintain a charming body shape.
