The dress is some sort of black/blue metallic satinish fabric, flat lined in cerulean lining fabric, and then underlined with navy. Closes with an invisible zipper and roll hemmed by serger with navy thread.
The train is a sequined organza that I got at Dongdaemun when I was in Korea. It was also roll hemmed, but using silver as the straight thread and navy on the loopers. There are a pair of iridescent buttons sewn to the top of the dress, and the train has loops that fit over those. The whole thing is about 5yd x 60".
The necklace is that rhinestone grid tape, also picked up in Korea, that I sewed double and attached to a piece of black bias tabe. It has ribbon end crimps, to which I still need to add a lobster clip. The same trim will be used around the bun on the wig (which isn't done yet).
