Sesame Street is the longest-running popular American Children’s TV series that premiered on November 10, 1969. Like the series, the characters gained overnight popularity and became every household names. Their costumes also gained equal fame. The Big Bird costume comes in a big yellow jumpsuit with red pants, and Elmo comes in fluffy red with big head and eyes popping out. Besides striking colors like red, yellow, green and blue, they come in an array of designs like the unisex jumpsuits with hoods while the frilled frocks for girls stand for cuteness personified. If you are a big group, each one can consider decking up in one of the character costumes.
