WORST: Lili Reinhart
Lili Reinhart missed the mark in this busy dress.

Millie Bobby Brown (13) rocked the blue carpet in this age-appropriate dazzling yellow dress.
WORST: Janel Parrish
The Egyptian mummy look is never a good idea.
BEST: Lucy Hale
The Pretty Little Liars star took a risk with this statement Fauto Puglisi dress - and it paid off.

BEST: Vanessa Hudgens
I can't make my mind up about this one, but Vanessa's belt deserves a 'best dressed' title on its own.
WORST: Madelaine Petsch
This ill-fitting playsuit looks as if it was made in less than 10 minutes.

WORST: Lori Loughlin
Lori's dress is just a tad too sheer and lace-heavy to work the way it should.
BEST: Rita Ora
Rita's bright pink dress is the perfect combination of fun and glamour.
