First Studio Ghibli film I ever saw, and it's still my favorite. Cosplaying Kiki was a dream come true.

I made the dress using a suiting fabric since it was a mix between black and blue, hand-drafted the pattern, and added princess sleeves and took the side's in just a bit to give it some shape. There are no zippers or closures needed, it literally just slides on and off like a shirt.
The shoes I found at Wet Seal.
The bow is over-sized and made from bridal satin with interfacing and slid onto a pre-existing headband.
