All hail the king of scumbro.

Show us a famous man who dresses like a slovenly pubescent teenager, and we’ll show you a sartorially-switched-on celebrity who knows exactly what he’s doing. The term scumbro, covered on The Daily last week, is the concept of slobtastic dressing made flesh and fabric, and refers to a certain subset of male celebrities (notably Messrs Pete Davidson, Jonah Hill, Justin Bieber and Shia LaBoeuf) who have an affinity for expensive streetwear, oversized track pants, ungroomed facial hair and socks and slides. The Wall Street Journal branded them “slob-ebrities”, and for better or worse, they are leading the conversation around what men’s fashion looks like in 2018.

However, scumbro style seems to be mutating, and it’s all Mr Jonah Hill’s fault. Mr Hill – whose somewhat unconventional penchant for baggy tie-dye T-shirts and Japanese streetwear has propelled him from endearingly nerdy actor to equally endearing “king of the scumbros” – made headlines today for an outfit that is… well. It’s something. It consists of a 1990s Phoenix Suns NBA basketball vest tucked into a pair of rather smart, tailored trousers. It is, by all accounts, an oxymoron of a look, and when street style Twitter account Four Pins tweeted it today­­­­ with the caption “GO OFF KING”, reactions were wild and varied. Who could dress with such wanton disregard for established menswear codes? Has Mr Hill found a way to bottle BDE and craft it into clothes? Are those chefs’ kitchen shoes?

Of course, commenters on the Daily Mail were quick to deride him, but to write Mr Hill off as style-illiterate is an oversight. Look closely at his outfit: that’s very possibly a Gucci belt. Do a bit more digging, and you’ll find that the actor is a consistent fan of Wacko Maria shirts, and was recently photographed wearing a pair of the new Prada Cloudbust sneakers. In the above baseball-vest-and-trousers picture, he was out shopping at Balenciaga. First rule of scumbro style: wear expensive clothes, but do so as though you don’t care that they’re expensive.

Still, Mr Hill is shifting the scumbro parameters. Some of us probably assumed that he would go on being a scumbro as we knew it for a while longer. But a quick fashion crib sheet: to define a fashion trend is to hand it a death sentence. It’s just not cool to be predictable. Ms Miuccia Prada, for instance, hasn’t built her brand on sending the same stuff down the runway every season, and when people call her a master of “ugly” clothes, what they really mean is that she has a knack for being – and staying – unpredictable. We’re not heralding Mr Hill as the new Ms Prada, but, well, he’s got people talking about (and, in some cases, excited about) his clothes. So, is this outfit from Mr Hill a scumbro levelling-up of sorts? And if so, with what witty epithet shall we pigeonhole it? Oxymorcore? Scumbro 2.0? Post-slobcore? Perhaps it’s better not to try at all.
