12 Style Lessons from the Best- and Worst - Dressed Men of the Week

Going for the three-piece look with a mismatched vest is a risky move. If you're going to try it out for yourself, follow Ryan Reynolds' lead and make sure everything fits impeccably.

The high-contrast vertical stripes on his pullover are bold, sure–but he balances things out by keeping the rest of the look muted. If you're wearing a statement piece, be sure to let it—and only it—do the talking.

There's a good way to do off-duty athletic style—but this isn't it.

This, on the other hand, is. From the slim sweats to the muted jacket, everything fits well and looks as appropriate on the streets of London as it would in the gym.

Malek really went for it with the blue-on-blue-on-blue thing. It's bright, and a bit much for most guys, but he manages to make it work. Just another testament to how damn versatile the color is.

The one trick to wearing a suit this bold? Confidence. Paul Feig has it. If you're wearing something with a big ol' windowpane check, you better have it, too.

OK, we've been over this before, but once again: The width of your tie should match the width of your lapels. (You know, approximately.) Russell Wilson is close, but his tie has just a bit too much heft compared to his jacket. Going just a little bit smaller would look more proportional.

The suit? Great! The sparkly slippers, two-tone tie, and stingy-brim hat? Not so great. All that over-accessorizing just distracts from the good things that are happening with Nick Cannon's tailored look.

Simple summer style is all about nailing the fit. It's just a blue shirt, chinos, and sneakers, but Reynolds manages to make the outfit feel like more than the sum of its parts.

This is for a role, right? Please tell us it's for a role.

We know it's the summer of the dad cap, but when the rest of your look already veers towards "off-duty dad," it might not be the best time to bust out your trendy headwear.

Ladies and gentlemen: The right way to wear a T-shirt with a suit. Keep things understated and let the fit be the focus.
