Describe yourself: what colour are your eyes? Is your hair straight or curly? Are you blond or dark-haired?, etc.
I have short hair, green eyes, and my skin is white. (You could also say that your skin is light instead of white.)
I have short hair, green eyes, and white skin.
Note--remember to use a comma after every item in a sequence until you reach the word "and." Also, it is important to keep your sentence parallel. The first two items in the sequence are nouns, but the third is an independent phrase. Change the last item to a simple noun (white skin) and you will be perfect!
