Big Sister, Little Brother Halloween Costume Idea 1: Little Miss Muffet and Spider
Adapt this classic tale for your children this year by dressing your daughter as Miss Muffet and your son as the spider. To make the Miss Muffet costume, purchase a plain blue or pink dress and a white lacy hat. Draw a spider on the front of the dress using black fabric paint. Braid your daughter's hair or purchase a Halloween wig.

For the spider, use black or grey sweatpants and sweatshirt. Use painted cardboard or card stock to make the legs and attach them to the sweatshirt. If you have a sewing machine, you can make the legs by sewing tubes of black or grey fleece. Turn them inside out and stuff with fiber fill. Attach to the sweatshirt.
