Vague Age: Barbie is often portrayed as being a teenager in several adaptations, but has also had pregnant married friends, gotten married herself, and gone through just about every career known to man throughout the doll's history.

Adorkable: Her appeal comes from the fact she's not as glamorous as Barbie, but doesn't feel ashamed of it. The Life in the Dreamhouse website even uses this word in reference to her.
Childhood Friends: She and Barbie have been friends ever since they were both little girls growing up in Willows, Wisconsin.
Commuting on a Bus: Barbie's best friend from the 1960s until at least the '70s, but Mattel only sporadically makes dolls of her after introducing Teresa.
Disco Dan: Life in the Dreamhouse portrays her as more accustomed to a 1960s lifestyle than a modern one.
Happily Married: Midge married Allan in the early '90s, and they stayed together up through the start of the following decade.
Progressively Prettier: Mattel originally introduced her to appease people who wished their dolls didn't look so unrealistically beautiful. However, she eventually became harder and harder to distinguish from Barbie.
Life in the Dreamhouse, both the show and the toys, show at least a little effort to make her homelier than Barbie.
Control Freak: Stacie organizes festivities for Chelsea's sixth birthday with "military-precision scheduling".
Lethal Chef: Subverted in the Barbie: Life in the Dreamhouse short "Happy Birthday Chelsea". She throws an entire carton of eggs, styrofoam container and all, into a bowl, along with the sugar box. She sticks the whole thing into the oven without a pan... and it turns into a perfect, already-decorated cake. "Baking can be hard work."
Retcon: She's often referred to as being a modern incarnation of Tutti.
Big Sister Worship: Chelsea truly admires her big sister Barbie and wants to be just like her.
Characterization Marches On: As Kelly, Chelsea was relatively quiet, unassuming, and unconfident, often relying on her big sister Barbie for guidance, although the Barbie: Life in the Dreamhouse series portrays her as a loud, sassy little girl who loves the spotlight and being the center of attention.
