The 90's is calling and they want...well, everything back! These groups literally bring a new definition to recycling. I haven't seen any bell bottoms yet (I'm disregarding your fashion choice PSY) but 90's fashion is making its way back to the future.

Just check out "Shout it out" or "Let's Dance" if you don't believe me.

Although some may not think it, he definitely has pulled some inspiration from the iconic time of when hip hop flourished. Don't forget his style for "Jo-ah" - even the sound was classic R&B goodness. However, I won't even uttered a word about what's going on in "Mommae," but simply that those braids, plaid shirts and tims are all signs of thrift shop heaven. All he is missing is the jumpsuit�.but we can leave that for Seo Taiji and the Boys.

Now I give credit where it's due. These ladies totally initiated the pencil skirt trend, but it is evident they have a one way ticket down the timeline. Maybe SM was trying to think out of the box but not only does "4 Walls" sound like the latest sound track for H&M but also their style is riding the 90's train all the way to the dressing room. Yet, who cares? f(x) is still fabulous in their flared pants and clean patterns. Talk about vintage.

Today's hottest rapper, but yesterday's trendsetter. His outfits are always calm and simple but still matching to his taste. Although I've yet to see him rock a bucket hat on stage (If he has, don't show me..), his "How do I look?" MV carries a real 90s feel. Even the video quality seems like it was captured on an old kodak.

"Ice-Cream Cake" may have a creepy futuristic sound, but those outfits are a blast from the past. Pencil skirts, polos, tucked in collared shirts, even hush puppies! The girls are practically time travelers with their modern chic looks yet seventeen magazine oldest fashion tips.

"Just Right" really oozed 90's fashion, from their oversized hoodies to the primary color scale of a crayola coloring box with all the blues, greens and yellows. Particularly, JR brought out the feeling of looking through my old baby album with that mixed pattern shirt.
