Deep berry, dark plum, burnt red...if it's deep and vampy, it's a perfect lip color for fall. If you don't have the perfect fall lipcolor, or if you just want more, here's a way to deepen any lipstick and get that perfect deep shade.
Black lipstick. Yup...that's right. With just a touch or black lipstick (or gloss), any lipcolor can be transformed. I personally use either MAC Black Knight lipstick or MAC Blackware Glimmerglass. The lipstick gives a deeper appearance while the gloss gives a sheerer, softer deepness. These products though, were both Limited Edition.
Some currently available products are:
Milani Sheer Dark Honey Crystal Lipgloss
Rimmel Black Diva Lipgloss
Hot Topic Black Lipstick
NYX Penelope Lipstick
OCC Tarred Lip Tar
