What lipstick works best for lecturing?

I use this technique for bridal, as it as long lasting effects, no matter what your day throws at you. Start off with a matching lip liner colour and outline the shape of your lips. Next, fill in the entire area inside the outline with your lip liner. From here, apply your desired shade of lipstick and take a piece of toilet paper (Make sure it's only one ply! Separate the layers if needed) and lightly place it on top of your lips. Grab a powder brush and some powder and lightly stroke across the toilet paper. This helps to set the lipstick in place and prevent smearing or other contraindications. Hope it works out for you!
