Dulcie Lungaarde Trighorn

Brassy, beautiful Dulcie becomes one of Beany's best friends, though her sassy manner at first sets many of the Harkness High crowd against her. She briefly dates Carlton Buell before he ends up with Beany, but her wandering eye doesn't suit the conservative Carl. She eventually marries Bartell Bottling worker August Trighorn, and by the end of the series, they have a tidy home of their own and a little girl named Gussie.

From Image Cascade:

Dulcie was a ponytail-bouncing, hip-swinging carhop at the Ragged Robin whom Beany somewhat took under her wing. Yet Beany was was often frustrated by her lack of sensitivity to most people. Dulcie tended to rub people the wrong way, particularly girls! She was best known for her liberal use of makeup, her ponytail that was the color of burnt sugar, and her tendency to be a "more-thanner" (More-thanning was the term that represented a girl's follow through of amorous affection.)

"...Dulcie in her red jacket, and her cheeks almost as red from the cold wind, and her lips even redder, because of lipstick wielded generously."

Her father squandered their already limited funds by involving himself in unproductive uranium projects. Although she had a propensity for bragging on her skills in sewing, dating and carhopping, Dulcie did have a soft side and a somewhat variable heart of gold. Her own shame of her home and background often brought Beany to her rescue.
