Held up for an over 12 hour day -- not once did I need to pull it up. Very happy with it. The only thing that kept me from giving it a 5 star review was that it had no padding at all. I thought it would have a teensy bit but no, it was all lace. Very pretty & ok if wearing a patterned shirt or dress but anything else & you will be poking through (if you know what I mean). A little bit of padding would have made this the perfect strapless bra for a chesty woman. I would still recommend it but with the caution that you may need to also invest in some nipple covers.
