Sometimes costumes are better when you do them together! This is a great option for a couples costume, friends, or your kids to do together. For this you will need matching set of leggings and plain t-shirt which can be found at Walmart or Amazon, as well as felt in the opposing color (Black if the clothes are white, or white if the clothes are black, or whatever color you want the dots to be really). Cut out the circles and place them ahead of time to know where you want them. Then you can use hot glue to attach them or sew if you are handy with a nail and thread! Super easy and another costume under $20 for Halloween!
