ideal, while unusual, stand-out features are another. A study performed by the University of Toronto found that the most attractive facial dimensions were those found in the average female face. However, that particular University of Toronto study looked only at white women. A study that used Chinese, Malay and Indian judges said that Chinese women with orthognathism where the mouth is flat and in-line with the rest of the face were judged to be the most attractive and Chinese women with a protruding mandible where the jaw projects outward were judged to be the least attractive. A 2011 study, by Wilkins, Chan and Kaiser found correlations between perceived femininity and attractiveness, that is, women's faces which were seen as more feminine were judged by both men and women to be more attractive. A component of the female beauty ideal in Persian literature is for women to have faces like a full moon. In Arabian society in the Middle Ages, a component of the female beauty ideal was for women to have round faces which were like a "full moon". In Japan, during the Edo period, a component of the female beauty ideal was for women to have long and narrow faces which were shaped like ovals. In Jewish Rabbinic literature, the rabbis considered full lips to be the ideal type of lips for women. Historically, in Chinese and Japanese literature, the feminine ideal was said to include small lips. Women would paint their lips thinner and narrower to align with this ideal. Classical Persian literature, paintings, and miniatures portrayed traits such as long black curly hair, a small mouth, long arched eyebrows, large almond shaped eyes, a small nose, and beauty spots as being beautiful for women. Eyes A study that investigated whether or not an eyelid crease makes Chinese-descent women more attractive using photo-manipulated photographs of young Chinese-descent women's eyes found that the "medium upper eyelid crease" was considered most attractive by all three groups of both sexes: white people, Chinese and Taiwanese nationals together as a group, and Taiwanese and Chinese Americans together as a group. Similarly, all three groups of both genders found the absence of an eye crease to be least attractive on Chinese women. In the late sixteenth century, Japanese people considered epicanthic folds to be beautiful. A study that used Russian, American, Brazilian, Aché, and Hiwi raters, found that the only strong distinguisher between
