If Alessandro Michele's influence at Gucci is any indication, the appointment of a new creative director can reinvigorate a brand not just in its design but also its public perception.

Since Michele took the lead in January 2015, Gucci sales have only continued to rise, and the brand has become a favorite for street style peacocks and Instagram It kids like Hari Nef and Petra Collins. Just ask Gucci's No. 1 fan, the six-year-old named Just Claudio, who was spotted in head-to-toe logos at the most recent London Fashion Week: Men's. "Mad sick," he said of the brand, which pretty much sums how an expensive, high fashion label has infiltrated the zeitgeist.

In August 2016, it was announced that Raf Simons would take over one of the most storied names in American fashion, Calvin Klein, as its new chief creative officer. The label has seen consistent success since its founding almost 50 years ago and is to thank for putting iconic hunks like Mark "Marky Mark" Wahlberg on the map.

Today, the #MyCalvins hashtag has nearly half-a-million posts on Instagram, and recent campaign stars include hugely influential personalities like Kendall Jenner, Bella Hadid, Justin Bieber, and even Kate Moss, as well as up-and-coming cool kids and scions like Selah Marley, Presley Gerber, Kacy Hill, and Tommy Genesis.

Simons is a master at creating collections that are lusted after years after they first walked a runway; recall his Virginia Creeper and Consumed collections under his own label. That savvy was on display at his namesake show earlier this week, in the "I Heart NY" sweaters and crop tops that sent certain corners of the men's fashion world into a tizzy.

So, it follows that he'll create equally iconic ready to wear at Calvin Klein, a brand that's known for its recognizable staples, from its underwear to its jeans. One of Simons' first creative acts was to work with the famed graphic designer, Peter Saville (who is best known for creating album art for the likes of Joy Division and New Order), on a slight redesign of the iconic Calvin Klein logo, making it all caps instead of lowercase. What this means in the short term is a likely surge in demand for items bearing the old logo, soon to become a coveted relic. Just consider that the re-worked vintage Gucci logo that Michele showed on a sweatshirt for spring 2017 is selling for over $1,000 online and in stores.

If you act now though, you still might be able to snag the look for less in vintage stores or on Etsy.

And in case you weren't already convinced, thanks mostly in part to the designer Gosha Rubchinskiy, vintage '90s sportswear logos like Fila, Kappa, and Adidas are everywhere on the runways and in the streets. In fact, to come full-circle, A$AP Rocky was spotted sporting a Fila t-shirt at the Simons' show during New York Fashion Week: Men's.

So, run, don't walk, to get those vintage Calvin Klein tees before it's too late.
