Absolutely gorgeous longline. Wore once for my wedding 2 years ago for 3-4 hours, and tried on a couple times later. Added elastic strap things to help keep it up, of which I have a photo in the album--could be removed fairly easily. Still looks amazing and is nice and snug. True to size fit.
Very comfortable fit. Unfortunately, it suffers from the same flaw as other low-back longline strapless bras: no support. The band and cups runs about a size small. However, even with a larger cup than I normally wear, the gore still doesn't tack because of lack of support since there is no band directly behind the cups (and the gore width is too big for me). Wish it had support, it is very comfortable and looks great.
