Alice
The black bow I wore was a remnant of my high school days, but you could easily make your own with a black headband, some black ribbon, and all purpose adhesive (or hot glue). When I was browsing online for costume ideas, just about all of them involved a blue dress. Since I'm not one for dresses, I looked for a blue top that I could wear instead. This one, which I found on Target's website (sadly it's no longer available) just screamed Alice to me for some reason. The black trim on the ruffles then inspired me to match it with black pants. Also, I just threw on those flip flops for the purpose of not being barefoot for the photo shoot, but I wore flats with hearts on them for the party.
Mad Hatter
The Mad Hatter's signature garment is his hat, so that was what I concentrated on. I used these tutorials, but also added a top to the hat. To do that, I made a circle the same size as the hat brim and then cut slits along the sides to create tabs which I could then stick to the inside of the hat. However, an easier method would be to cut slits along the cylindrical part of the hat, fold them over, and then glue a circle to them.
Cheshire Cat Ears
Materials:
*Purple headband
*Purple felt
*Pink felt
*All purpose adhesive
Directions:
*Cut out two diamonds from pink felt and two, slightly larger diamonds from purple felt. Center the pink diamonds on the purple ones and glue down. (As you can see from the picture, I actually made felt triangles and glued them on at the end, but this method might be a little easier and then there is no "right side" to the ears.)
*Fold the diamonds over the headband, aligning the edges of the two sides, and glue together.
