My sister is = Mi hermana es.../Mi hermana está... If you're saying that your sister is blonde, you should write: Mi hermana es rubia. Note that the adjective (rubia = blonde) has to agree with the subject (hermana = sister). If you want to say that your sister is doing something, use ésta. For example: My sister is reading. - Mi hermana está leyendo.
