As much as they are an age-old fad, wearing corsets initially could lead to a certain amount of discomfort . You would feel back pain, a sort of tenderness of the muscles. This is because the corset is trying to check the way you carry yourself as many tend to slouch sitting or standing. If breathing causes sharp pain, it’s not good. Season your corset to allow some breathing comfort.
Another is gassiness. Of course, as you wear corsets, the abdomen is tightened and so eating food that may be gassy could be uncomfortable. Food like sweet potato, raw vegetables or soda could cause that gassy feeling. If you feel nauseous, your corset may be laced too tightly. Remove and breath.
