Do you still need underwear to wear a one-piece bra?
Underwear can be worn outside the bra. At present, most of the one-piece corsets on the market will have a crotch design, which is also for the convenience of the wearer to go to the toilet. Therefore, the correct way to open the conjoined corset is this: first put on the conjoined corset, and then put on underwear outside the conjoined corset. When the wearer goes to the toilet, just take off his underwear.
