OMGosh! I wore this bra for the first time the entire day with no discomfort at all. I was hosting a Bridal Shower which included decorating and set-up, serving food, dancing, cleanup, and more...I forgot I even had on a strapless bra. Yes, it is that comfortable and secure! It stayed in place the entire time - no roll up or having to hike it back up. Im a 36DD...I would definitely recommend! Love it!
