The first time I saw Miku's design in 2008 I fell in love with the colorful, cute, and fun outfit and just had to cosplay her.
The top is made from several yards of gorgeous silver silk I found on eBay for $30, and is lined with a grey cotton and interfacing for stiffness. It is a modified vest pattern with four darted panels in the front, three in the back, and a button up shirt pattern for the collar. It closes with an invisible zipper down the front. I decided to do a ruffle trim as opposed to pinked edging to make the color stand out more. I made the trim by cutting strips of teal fabric and knife pleating them before attaching them to the vest. The vest accents are done with gold and teal metalfinish cardstock and the "Vocaloid" letters were bought at Michael's and sewn on.
The skirt is a store-bought black knife pleated skirt and petticoat. I added the teal edging to match the ruffle trim and made the gold accents from cardstock. The side belt is a teal belt with darker accents painted on. The tie is more matching teal fabric and the accents are made from black plastic and glued on.
The boots are a combination of 1) pleather thigh high boot tops cut off from the original boots which had uncomfortable stiletto heals and 2) a pair of small-healed shoes. I sewed them to each other and painted the bottom of the shoes teal. I then hand embroidered the "piano key" accents on the side of the boots. The light-up sleeve panels were bought online and wired to battery packs on wristbands I made from industrial velcro. I also purchased the earpiece parts of the headphones, which by boyfriend kindly screwed into a headband using a powerdrill.
