I found this Madame Alexander doll at the thrift store for $1.99.
This was really a steal. They usually put Madame Alexanders into the glass case and charge $14.99 for them.
This doll is named Colleen and she is from the Portrettes series in 1988. She is a Cisette doll and is 9.5 inches tall.
It appears to me that this series wore fashions meant to evoke historical fashions. I don't think that this dress represents one particular decade, though. It's like a 1830-ish ball gown seen through the lens of 1980s fashion. The blue eyeshadow is also very 80s.
She is missing a stocking and a shoe, and there is a dab of glue in her hair where it looks like there was some kind of ornament.
Overall, she's in good condition.
I was happy to find her!
