- 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.
- Happily Married: Allan married Midge in the early '90s, and they stayed together up through the start of the following decade.

- Attention Whore: Oftentimes it seems like Raquelle only hangs around Barbie in hopes of outshining her.

- Friendly Rival: Since she still hangs out with Barbie and her friends, she can't hate her that much.
Voiced by: Charlie Bodin (Life in the Dreamhouse)

- 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.
