To contradict this generalization as it pertains to Shakespeare's Romeo and Juliet, it is Romeo who consents to attend the fete that the Capulets have and look. When he does see Juliet, it is Romeo who falls instantly in love. Therefore, Romeo is the one who chooses on looks. Juliet is hesitant to touch him when he offers her his hand as "a good pilgrim"; she is not the one swearing by the moon, either.
Earlier in the play, when Lady Capulet asks Juliet about Paris--"What say you? can you love the gentleman?"--Juliet replies,
I'll look to like, if looking liking move./But no more deep will I endart mine eye/Than your consent gives strength to make it fly. (I,iii,101-103)
It is again Romeo, rather than Juliet who is infatuated with appearances in Act II. For, after he scales the walls of the Capulet orchard, he stands in awe under her balcony:
But soft! What light through yonder window breaks?
It is the east, and Juliet is the sun!
Arise, fair sun, and kill the envious moon,
Who is already sick and pale with grief
That though her maid art far more fair than she....
See how she leans her cheek upon her hand!
Oh! that I were a glove upon that hand
That I might touch that cheek! II,ii,1-25)
