First, some ground rules:

- These outfits are ranked definitively from worst to best.

-All 131 original Baby-Sitters Club series books are included. F$%d the Little Sisters series.

-When more than one person appears, the cover is ranked based on the most noticeable/important outfit, as determined with a special secret science.

- Since Claudia Kishi is obviously a style icon, the bar is set higher for her and she has to work harder to compete with the other girls (at least when they actually put effort into their looks) to prevent her from just completely dominating the top 25. This is also known as the Dancing With the Stars rule.
