In case you didn’t hear the news, our alien overlords have crash-landed onto US soil and it can only mean one thing: there’s more of them to come and – like every major event – you’ll be needing a new fit for their arrival. We’re going all out for the occasion, donning alien-themed looks that’ll have our new visitors feeling straight at home (basically, no one’s allowed to greet the aliens in sweats and a hoodie). But, in case you don’t have anything like that in your wardrobe, we’ve compiled a list of some of the essentials you’ll likely be needing soon. Don’t be underdressed for the aliens’ arrival: you wouldn’t want to make a bad first impression.
