While we're always excited to see trends coming from the runway to the red carpet, there are times when they're just plain wrong. We've rounded up looks of the week where some stars hit it out of the park but others weren't so lucky (A for effort...?).

From knowing when to dress up to dressing down in style, the stars were out and about on the town at big events like the CFDA and CMT Awards. Jessica Chastain pulled off the sheer, cut-out look impeccably, while Saturdays singer Mollie King took it a bit too far. Fergie and Duchess Catherine continued to ace pregnancy style, while others seemed to forget what event they were attending.
