Grammys fashion hall of fame and shame

If the 2015 Grammys had one standout fashion moment, it was Rihanna’s arrival in a swirl of hot pink tulle that was Giambattista Valli’s Empire waist bubble gown.

Pharrell Williams, right on both photos, in an Adidas short suit made using 3M light-reflective materials that turn the light gray fabric a blindingly bright white when photographed with a flash. Neither a worst-dressed or a best-dressed look, it was definitely one of the more novel.

Pharrell William’s outfit at the 2014 Grammys might not have exactly been high fashion – jeans and a red Adidas track jacket layered over a T-shirt – but the outsized Vivienne Westwood Mountain hat he chose to complete the look launched a social media frenzy and catapulted the hat to instant icon status where it has remained ever since.

Beyonce probably deserves her own hall of fame category for head-turning Grammy looks like this sheer, white floral lace gown by Michael Costello that she wore at the 2014 awards.

Katy Perry struck just the right note at the 2014 Grammys in a full-length Valentino Couture gown with black musical note embroidery (the score to Verdi’s “La Traviata�).

Beyonce wore a graphic black-and-white Op Art-inspired crepe jumpsuit by Osman Yousefzada in 2013, proving that you don’t need to wear a gown to make a style statement.

Lady Gaga has served up no shortage of memorable red carpet looks (meat dress, anyone?), but the Giorgio Armani Privé dress she wore on the 2010 Grammys red carpet -- strands of pink, glittery wire that seemed suspended in orbit around planet Gaga and accessorized with a massive silver spike orb -- struck the perfect balance between elegant high style and out-there interplanetary weirdness.

If there’s one dress that would definitely make it into our fictitious Grammy Red Carpet Hall of Fame on the first vote, it would be the green tropical leaf print Versace dress worn by Jennifer Lopez in 2000.

Arguably the most famous dress in Grammy history, this sheer, gravity-defying number had a neckline that plunged well past the belly button, cinched just above the pubic bone with a sparkly brooch and required the strategic deployment of double-sided fashion tape to keep street legal.

In 2015 Madonna turned out in a butt-baring burlesque matador outfit by Givenchy.

Nicki Minaj’s blood-red custom Atelier Versace silk dress and hooded cape ensemble at the 2012 Grammys stuck with us not just because of the Little Red Riding Hood meets Flying Nun vibe but also because she accessorized the look with a guy dressed like the pope.
