My Little Pony

With a cute modest dress and a little bit of time and money on your hands, you too can be your favorite My Little Pony! This costume does take at least 24 hours, as the Model Magic needs time to set. If you don’t have the time, patience or money for the entire costume, you can always don a cute princess style dress (maybe your modest prom dress from last year?), make only the horn and go as a unicorn!
