Can I give black lipstick application advice? (Ignore the rest of this comment if it's unwanted!)
Outline and fill in your lips first with a smudge proof black eyeliner pencil (mistakes can be fixed with a qtip dipped in micellar water) and set the liner with translucent powder.
(To set with translucent powder, use a makeup sponge or brush lightly dipped in powder, tap the excess off, and gently press it onto your lips.)
Then apply your black lipstick on top, staying within your neatly drawn on lip outline.
For extra staying power: gently blot that first coat of lipstick with a tissue till it barely transfers anymore, and set your lips again with another light coat of translucent powder and apply another coat of lipstick on top.
