She has also been cited as a sex symbol. As the biggest pop star in music by the mid-1990s, Carey's "first years as a pop star were extraordinarily fruitful but restrictive". In the late 1990s, after separating from Mottola, Carey adopted a more provocative and less conservative image than had been previously seen and began wearing more revealing clothes. Her album "Butterfly" has been credited for revamping Carey's image as a pop star where she began to embrace hip hop and R&B themes and fully come into her own self. Emilia Petrarca of "W" stated that "Carey is uber-cautious about cultivating her public image" but that when it comes to style, she is "more do than don’t".
