Chelsea Kelly Roberts is Barbie's youngest sister. Chelsea was originally called Kelly. Kelly made her debut in 1995 and retired in 2010. Chelsea replaced Kelly in 2011. Kelly is now featured in the "Barbie: I Can Be" toy line. She is small, with blue eyes and blonde hair a little lighter than Barbie's. Chelsea has many friends, which are also available to buy as dolls. Her friends were sold after the first Chelsea dolls were made in 2011. Special limited edition occasional dolls were sold in Target stores until 2015. In 2014, a new line, Chelsea and Friends was created and included 6 dolls, 2 were different versions of Chelsea and the rest were friends. The line also included Darrin, a boy doll, similar to Tommy, which was the first boy Chelsea doll made. As of 2015, Chelsea dolls now have painted on tops and removable skirts/shorts instead of removable clothes for mix and match play. Chelsea dolls are still sometimes sold with clothing. In 2017, a new line named Club Chelsea was introduced with 7 different dolls which have bigger eyes. There are no official Barbie separate clothing sets for Chelsea, all Chelsea clothes are sold with dolls.
