On that beach clothing is entirely optional.
- 2004, Paula Begoun, The Complete Beauty Bible: The Ultimate Guide to Smart Beauty, Rodale Inc., -ISBN, page 419:
  Do you need to wear eyeliner? As with any makeup step, eyeliner is completely optional. From an artistic perspective, if you are wearing eyeshadow, I almost always recommend wearing eyeliner, unless your eyelids and eyelashes are obscured by the eyebrow area. Eyeliner is a basic part of an eye-makeup design because it shapes and defines the eyes and makes the eyelashes look thicker.
