When contouring the eyes, do not fall into the trap of tight lining the bottom lid in black.
While tight lining the upper lid will lend to the illusion of longer lashes, though extensions have been used in this picture as well, tight lining the lower lid makes the eye appear much smaller.
Rather contour the crease of the upper lid and corner of the eye with eye shadow which will open up the eyes. If you forego the black liner on the lower lid you won’t have to contend with the black gumph that collects in the corner of the eye or with raccoon eyes.
Don’t forget to fill in and comb your eyebrows, framing your eyes and polishing your overall look.
