One day when you grown up and you're ready to dress like an adult, print out this picture of Jay at the New York City premier of The Great Gatsby, a film for which he co-created the soundtrack and is listed as executive producer, and bring it to your tailor. Hope he can fit you in something that comes close to the flawless charcoal windowpane two-button suit Jay-Z wore last night.

Hov took Leonardo DiCaprio and Tobey Maguire (two well-dressed gentleman in their own right) to sartorial school on the red carpet, and gave Hollywood a clinic on how to dress like the richest, most powerful person at the party while he was at it.

The first quarter of 2013 has been huge for Jay-Z—the cover of Time Magazine's Most Influential People issue, a shoutout from President Obama, and an entirely new business venture, just to name a few of his recent accomplishments. Jay was brought on to give the 1920s film a modern update by lacing the Jazz Age cool of the era with a contemporary, hip-hop twist. Judging by how well he managed this update on a very classic menswear look, no one could have done it better.
