Jennifer Lopez has gone from car crash couture to Hollywood glamour since she first came on the scene in 1998. She was one of the original R&B cool girls, and she loved to prove it through her bold fashion choices.
We've tracked J-Lo's block's style evolution from the start of her Jenny from the block days. (17 years on, she still loves a cut out dress.)
Her hits and misses? How could anyone forget the Versace dress she wore to the Grammys in 2000, or the white trouser and crop top look from the 2000 MTV VMA's complete with a bandana, big hoops and ghetto girl hair.
