This dress is brand new, never worn, never altered. I purchased it in 2016 for a fall wedding. We ended up changing our wedding date to mid-summer and I went with a different style due to the summer heat. It is absolutely beautiful - the beading, the lace, the detail. I have held onto it for some time because it has been so hard to part with, but it is time for it to go to a bride who will show it off. There are a few small areas on the lace overlay that appear darker - it seems to be a normal part of the coloring of the dress. Again, this dress has never been worn for longer than a try-on, so if it is a discoloration, it is just from being stored. I have not tried to spot clean. From the Stella York website: “Featuring handcrafted Diamante beading, this lace wedding dress features a plunging back adorned with sparkling jewels. The glittering shoulder straps highlight the fit-and-flare silhouette, which hugs every curve of the bride’s frame. The luxe skirt flares just below the knee and is embellished with lace motifs and shimmering breading. This backless wedding dress closes with a zipper under crystal buttons.”
