Red lipstick is a permanent staple in our makeup stash, obviously. But something about a pair of straight matte red lips (nothing too bright or glossy) just screams “September.” The dark red shade Michelle Trachtenberg is wearing matches her skin tone to a T, and we love how the color perfectly defines her lips.

Some of our faves: Clinique Long Last Soft Matte Lipstick in Red Hot, $14, L’Oreal Colour Riche Lipstick in True Red, $5 and NARS Semi-Matte Lipstick in Fire Down Below, $24.
