This is Cissy by Madame Alexander.
The dress is an original, designed and sewn by a talented woman who wanted the outfit to look just like one her mother wore to church in the 1950s. The dress under the coat perfectly matches the coat, scarf, and hat.
She is an original Cissy except for her wig which is not right. Usually, you can buy replacement wigs for old dolls who wear wigs, but not for Cissy. Nothing was available anywhere. I could not find an appropriate replacement wig for her, so she is wearing a wig that at least fits her head, but is absolutely the wrong style.
Otherwise, she’s one of the original fashion dolls and quite a beauty. Also, most definitely pink.
