Keira Knightley has got a natural straight hair that suits her perfectly. To get this hairstyle you must get a good cut chin hair length, graduated bob add the waves. This finger wave style can be used to soften a bob and very much similar to a Marcel Wave which makes it a best way to copy. Try to comb hair in Finger Waves which is the traditional way to style the hair. Apply a hair lotion through the wet hair and with the fingers mould the hair creating soft waves. This is the best way to bring 1920’s hairstyle into the present time.
