I am always reluctant to purchase strapless bras/bustiers online without trying them on first. Strapless undergarments tend to not stay put. They also can be too high on the bust or in the back, where they show out of the top/dress I am wearing. This is not the case with this bustier! It cups really nicely, stays put and its low enough in the back that nothing peeks out. In addition to its practicality, I think it's sexy. Perfect for my wedding day!
