The three girls are wearing the same outfit, but in different colors. Also the use of different accessories makes each girl look unique. I like that on each skirt there is a different thing on it, which makes the skirt exciting.
This is a great example of the poodle skirt, which was popular in the 1950s. These skirts were full-circle felt skirts with a poodle applique on the side. Rhinestones would commonly adorn the poodle as well. 3.18.16.
