When in Doubt, Wear a Suit
While this movie star may have floundered early in his career, he has since learned that it's better to dress up than down. Gosling has put away his tuxedo tee and opted for a well-tailored suit for most events with members of the press in attendance.
While a suit might not be as formal as a tuxedo, it's incredibly versatile because you can combine it with different shirts, ties and pocket squares. So if you want to dress like one of Hollywood's best but you don't have the cash to do it, invest in one suit that fits you well and wear it as many ways as you can. A single good suit will serve you better than several oddly-fitting or obviously inexpensive ones.
