The dress I am buying has a built in corset. When I tried it on I was told to remove my bra and everything held in place just fine with the dress itself. But I'm wondering, are you SUPPOSED to wear the dress with a corset bra/bra even though its built in or do you just wear it as is? Or is it more a matter of personal choice. Wondering if I need to purchase specific undergarments once I go back to make the final payment on my dress. Thanks!
