You might think the star of the upcoming "Nick and Norah's Infinite Playlist" is an unlikely candidate for Steal That Style. Sure, the "Arrested Development" standout has a face that can imply earnest awkwardness in a thousand different ways, but a fashion icon?

We would argue that Michael Cera possesses in spades what many of his jeans-and-T-shirt-clad peers lack: a unique and consistent personal style. It's called grandad chic, with cardigans, sports coats and rumpled shirts tucked into high-waisted slacks, all worn without apparent irony.

It may not be the most cutting-edge look out there, but it's his and he owns it and, damn it, that's why Michael Cera's style is a perfect target for a little thievery.

Cheap Monday Loose Shirt
Low-price jeans and casual wear chain Cheap Monday has been a go-to spot among hipster types in its native Sweden for some time now. Fortunately, the brand's distinctive threads, like this great, Cera-esque red check button-down, are now available in the U.S., too. ($65.00 from UrbanOutfitters.com)

More superbad wardrobe suggestions after the jump.

Acne Jeans Acapulco Cardigan
It's difficult to tell from the picture, but Cera is sporting a very relaxed blazer in a soft fabric. Frankly, that sounds like a lot of work when a navy cardigan, like this indulgent number from Acne Jeans, will achieve the same comfortably avuncular look with ease. ($299.00 from eluxury.com)

Original Penguin George in Monument / Black
If you're going to put together a version of Michael Cera's unselfconsciously retro outfit, you have to wear at least one item from Penguin, the undisputed kings of the old geezer meets hipster genre. These kicks even share a name with Cera's hapless "Arrested Development" character. ($65.00 from PenguinClothing.com)
