Using figurative speech, describe a beautiful person's features?

Use Concrete Examples The best place to start with your character description is with concrete examples. To say that a character has "brown hair" doesn't create nearly the image as saying that a character has long dreadlocks. Think about what kind of clothes the character wears, whether a character has freckles or moles, whether her teeth are straight or crooked or what kind of scars he has. 
Make Examples Do More Avoid overloading your reader with a list of details about each character's appearance. 
To create a vivid image of your character without spending a lot of time on minutia, choose details that have a ripple effect on the description.
