Here are some options:
* Nani maka: This literally means "beautiful eyes," but it can be interpreted to include the eyelashes.
* Nani ka maka: This means "beautiful is the eye," emphasizing the beauty of the eyes, including the eyelashes.
* Nani ka ʻili o ka maka: This means "beautiful is the skin of the face," which can be used to describe the eyelashes as a part of the facial beauty.
You can also use a more poetic approach by combining words to describe the specific characteristics of beautiful eyelashes:
* Lōʻihi a me ka nani o ka ʻūlū: This means "long and beautiful of the eyelash."
* ʻŪlū lōʻihi a me ka ʻālohilohi: This means "long and shiny eyelashes."
Remember, the best way to convey the meaning depends on the context and your intended message.
