This cardigan, a cream-colored, long-sleeved, cable-knit cardigan, becomes almost iconic for Bella's character in the film.
The reasons for this choice could be:
* Visual consistency: The cardigan acts as a visual anchor for Bella's character throughout the film, creating a sense of continuity even as she experiences emotional turmoil.
* Symbolic meaning: The cardigan, with its warmth and softness, can be interpreted as representing Bella's vulnerability and the comfort she seeks in the face of her heartache.
* Costume design: The filmmakers may have chosen the cardigan for its classic, timeless style, which reflects Bella's own personality and her often understated look.
The cardigan also serves as a stark contrast to the dark and brooding aesthetics of the vampire world, further emphasizing Bella's humanness and vulnerability.
