    Great strapless

    I was skeptical but very happy after wearing all day and forgetting it was a strapless!! Wish they offered unique band sizes like a 33, but will buy more styles from here!

    Comfortable!

    Definitely a little tight and stiff at first, but after the first hand wash very soft and comfortable after the first wear! I wore the flex for a whole evening and did not worry about any slippage.

    It wasn't great for larger chests

    I wanted to love this as it is so hard to 1 fin bras for larger chests that prefer to be more modest and 2 to find a strapless one that doesn't fall down. Unfortunately there was too much padding in the bottom of the bra that lifted my breasts too much and made the whole bra fall down. I think I need to return it :(
