I have had this daylily for a long time (decades, really) but with deer predation and also a bad (too much shade) location, I haven't seen regular bloom on it, and I don't recall ever seeing rebloom.
That said, when it has been in (unmolested) bloom, I have to say that the blooms are lovely - and I am not one, generally speaking, who is a fan of creped daylilies. But on this flower, it works - and the name very much reflects the beauty of the bloom; the color and texture of the bloom are evocative of a fairy tale ball gown.
My only problem with the daylily is that the scapes are a bit shorter than I like (26", but at the time, that's more or less the height they all seemed to be). So this daylily needs to be positioned such that you can enjoy the flowers even though those scapes are short; mine is at the bottom of a hillside, right behind the (2 ft high or so) retaining wall.
A bonus for those who care about such things (and one reason why this daylily stays in this garden, and will go with me if ever we leave) - it has excellent rust resistance (a rating of 1.0).
