Jennifer Lopez
The Grammys is cracking down on risqué wardrobe choices. Say goodbye to outfits like these:
J.Lo's infamous Versace gown from 2000. Violations? "Bare under curvature of the breasts," for one.
Rihanna
This revealing RiRi number from 2011, which does not " adequately cover" "female breasts" and "buttocks."
Pink
This seemingly nude bodysuit worn in 2010, as "thong type costumes are problematic." (Big year for thong type costumes!)
Pink (Again)
This gothic (and "sheer") 2003 red carpet look, "that could possibly expose female breast nipples."
Lil Kim
This plunging 2004 outfit, on which "the genital region" is not "adequately covered so that there is no visible 'puffy' bare skin exposure."
Toni Braxton
This 2001 half-gown breaks cardinal rules number one: "Avoid exposing bare fleshy under curves of the buttocks and buttock crack."
Sisqo
For the record, you can still wear this though.
