See what looks are sizzling -- and fizzling -- on the red carpet!

In our weekly roundup of the looks that are gaining fashion ground (and the ones losing their style street cred), we saw ladies daring to bare, a few metallic moments and a hairstyle that’s better left at the gym than worn on a red carpet.

Up: Bra-Baring Tops. It seems we have done a total 180° from last week’s only-kinda crop tops. This week’s trend is all about showing skin, with leading ladies baring their (sorry, but we really can’t resist this) over-the-shoulder-boulder-holders. Keri Russell (left) proved that you don’t need a glamorous dress to make a statement with her textured sheer tank revealing black undergarments at her Dawn of the Planet of the Apes premiere. Nina Dobrev also showed off her bra with a see-through top paired with a dusty-rose maxi skirt (both Elie Saab) while attending the designer’s Fall 2014 Couture show. The underwear-baring trend has been around for some time now and we don’t expect to see it fading (as long as Kim Kardashian is on the scene, anyway).

Up: Metallic Silver. Looking for a little extra oomph in the wardrobe department? This latest trend might be just what you need. Chloë Moretz (center) stood out amongst the crowd donning a head-to-toe chrome ensemble at Paris Fashion Week. Also attending the same show, Pink rivaled Chloë’s outfit with a dress featuring a highly-embellished silvery top. But nothing divided the StyleWatch office more than the gleam coming off of J.Lo’s Atelier Versace pants/dress creation (and PEOPLE readers are split as well)!

Down: Off-Center Topknots. No, Kate Hudson (right) didn’t give her hairstylist the day off — that’s the real Leaning Tower of Topknot on the red carpet. Though a high topknot is a favorite among many stars, this messy, off-center version looks ready to topple — and the loose tendrils accentuate the “fresh from Pilates” vibe. An undone updo is one thing, but we don’t expect this “my dress cost $10K and my hair took fifteen seconds” look to catch on in Hollywood.

Which of these trends will you try? Which will you skip? Tell us in the comments!
