Friend told me wear one after pregnancy. Also helps your back alot

Waist trainers are really just to give you a shape again 👍🏽 totally work cuz I wore mine for two weeks (during the work hours) and my husband even saw my hourglass shape once I took it off for a break! I heard of mamas using belly bands though for post birth. Helps keep everything tight better than a waist trainer 👍🏽
