Round eyes look good with almost any type of eyelash shape. The key is to watch out for proportions and not let the longest length of your lashes be longer than the height of your eye. The only lash style to avoid is the 'doll' eye shape where the middle lashes are the longest and darkest, as well, avoid dense lash styles with no separation. This lash shape & style will make your eyes appear smaller and beady. Other than that, you're pretty much good for everything else!
