It's finished! My sequin trench coat is finished! I finished it this Saturday and quickly went to the closest train station to take pictures, and the train just happened to pull up. It was a very chilly day and the coat did little to keep me warm but I looked glamorously cold. The sequined pieces are lined in flannel, and the coat is lined in a teal bemberg rayon.
I love the way it fits, stressing over my muslin fit really payed off. I kept the coat true to the original pattern but I omitted the straps on the sleeves, and added a tab on the shoulder. The hardest part about sewing this was the buttonholes. I had to sew them through some tearaway interfacing to get the thread to stay even with the uneven sequins. They even got stuck at the front seam, and I had to rip out a buttonhole and start again. GRR.
Now that this coat pattern is fitted I might even make it out of a more practical fabric! or maybe not, it's more interesting to be unpractical. The coat is now on display at Fabricland, where I work, hopefully it will inspire someone to make something else out of sequins.
