Many complain of their looks, but none of their brains.

(Other Authors and Sources)

Italian proverb

Also noted as a Jewish or Yiddish proverb.

This is also often cited to Sally Koslow, Little Pink Slips, ch. 5 (2007); it appears there as ""Many complain of their looks, few of their brains," but is described as an unoriginal needlepoint on a pillow cover.

See also La Rochefoucauld for a similar construction.
