for most of my adulthood, I've been searching for THE perfect bra to wear and after hearing my grandmother's advice for years and years to try an "18 hour brassiere," I bought one last week to try it.  I am so disappointed.  The fit is terrible and not true to size (incredibly small) and the fabric is a scratchy mess.  I had bulges coming out in places I never knew I had.  I did wear the bra for several hours, hoping that it would maybe relax a bit, but after four hours, the straps just dug into my shoulders causing more uncomfortableness.  I really wanted to like this bra, but I can't.  I would take the bra back, but because it's unsanitary to return a bra, it's getting thrown in the trash.
