This is one of my elf costumes. It can double as a fairy costume as well, but I designed it with "elf" on my mind. I used a prom dress pattern with a few added "leaves", no boning as I didn't have any and didn't want to go buy some, and shortened it to near half the length of the original (which would have been far to long for me anyhow). The fabric was something I already had on hand (you've probably noticed by now that I wasn't in the mood for spending money) and helped dictate the length of the dress. The green fabric was mostly a scrap when I found it, but I still managed to make every inch count in getting what I wanted out of it.
The caplet I'm wearing was made by sewing several triangle of cloth into a circle. I then cut a hole into the center of the circle big enough for my neck and finished the raw edge with bias tape made from the same cloth. Then I hemmed the opening in the front of the caplet and added hook n' eyes and the acorn buttons for decoration. I used pinking sheers to the finish off the raw edge at the bottom of the caplet for a more rough and leafy look.
