4. Dark Lipstick in Summer

Deep, vampy lip shades are usually reserved for the colder months, but wearing a dark plum or burgundy lipstick in summer is a daring twist that pays off. When paired with glowing, sun-kissed skin and minimal eye makeup, a bold dark lip can look unexpectedly fresh and stylish. This trend—spotted on runways and in fashion editorials—proves that seasonal color rules are made to be broken for a stunning, modern effect.
