Skinny jeans, babydoll tops, and flats (all as part of the same outfit). YUCK! Way overdone. It just doesn't look right. And skinny jeans in general. They just don't look right on anybody.
More no-no's:
animal prints
emo/goth-style clothes (all black, jeans with zippers all over, etc.)...
Wilder? I remember reading these books back in elementary and middle school. There's this "side" series by Roger Lea Mcbride, The Rose Years, where it describes life from Rose's view as she grows (she's Laura's daughter).
There's also this other series, and I can't for the life of me...
