Select a base color. In warmer weather, your legs are usually a little bit tanner than your face, so using the same foundation as a base for your legs will result in streaky, chalky or ashy legs. Go a shade or even up to three shades darker, depending on what color truly matches your legs. If your coloring is consistent, you can use the same shade you already have in your makeup kit.
Thicken your base. Leg makeup has to provide more coverage than face makeup, especially if you're hiding dark bruises, tattoos or spider veins. Select a pressed powder that corresponds with the foundation base you're using. Pour enough foundation into a small dish to cover the parts of your legs you want to conceal or contour. Use an orange stick to carve out a portion of the powder from the compact and tap the stick into the powder to break it up just enough to mix with the foundation. Stir the two together until the foundation thickens to a consistent base.
Apply your leg makeup. Dip a fan-shaped cosmetic brush into the dish with your mixed leg makeup and coat the tips. Brush the makeup over any blemishes, including veins. Apply fine layers, one by one, until you're fully covered. Remember it's easier to apply more than take off too much and start over. Once any discolorations or marks are covered, begin to contour your legs. Brush another fine layer of foundation along the sides of the shin bones and along the lines of the calf and thigh muscles. Blend your brushstrokes with light, feathery strokes.
Set your makeup. Since your legs are bound to brush things all day or night, including each other while walking, sitting, dancing or driving, you need to set your leg makeup just like you would your face makeup. Using the included applicator, pat on a light dusting of powder over blemishes. Use the fan brush to dust strokes of powder over contoured areas.
Use two mirrors, one in front of the other, to double check for consistent application along the backs of the legs.
