It was all about rebelling in the 1990s and the grunge style became the "look" for all rebelling teenagers. And guess what? Yep, it's coming back. The fashion rebellion style of the grunge style is having a comeback, but it's not just for rebelling teens anymore.
The 90s grunge fashion was all about looking like you didn't care at all about fashion. You wanted to look like you rolled out of bed, threw on the first thing that you found on your messy floor and ran out the door without brushing your hair or putting on makeup. The look was that you wanted to look like you didn't even try.
The modern grunge trend adds a little bit more thought to the fashion equation (think more grunge glam). It's still about looking effortlessly cool, but you might have to try a little bit to pull of this look. Here are some staple modern grunge pieces that will give off the effortlessly cool vibe.
