Sandi is President of the Fashion Club.  She's very competitive, gets jealous easily, and has control issues. She's also pretty pretentious in her speech, although none of the words she uses are too big, but she's trying.

Her best friend seems to be Tiffany, which is going to cause her problems later, as Tiffany has been kissing up to both Sandi and Quinn, apparently waiting to see who's going to win their ongoing low-level conflict, which recently took a turn for the worse for her when Quinn set her in her place after a summer of tutoring.

Her only other friends appear to be Stacy and Quinn, which is going to be even more of a problem, as she and Quinn aren't really friends, and they both know it. Stacy is just plain desperate to fit in, and is going with Sandi out of fear more than anything.

Sandi seems a lot like her mother, and has two younger brothers that she can't stand, and they can't stand her. She also has a cat named Fluffy.
