2. 1990-Columbia-'Vision of Love' Carey's debut single. The song was originally featured on Carey's demo tape which aided her sign to Columbia Records. The video as well as the lyrics connote a sense of faith and prayer as it is set in a cathedral like setting. In reference to Carey's image here she looks very natural, she does not not have a lot of make up on, she has long, golden, natural curls and is wearing black clothing. Her look here is not very sophisticated. This song alone influenced the singing careers of RnB singers Beyonce and Christian Aguilera.

5. 1997-Columbia Records-'Honey' This single was taken from Carey's sixth studio album, Butterfly . 'Honey' was Mariah Carey's third album to reach number one on the Billboard Top 100. Following her separation from her former husband and Columbia Records Executive, Tommy Mottola, this album saw a totally diverse side to Carey in regards to her image as well as her style of music. This album pushed Carey more into the RnB/Hip Hop market compared to her other albums which had more of a pop feel. Due to her separation from Mottola Carey had more control over this album and the single 'Honey' seems to explore that 'freer side' as throughout the video she is provocatively dressed and shows a more sexual image of Carey than previously seen.. She wears a little black dress, tight black swimsuit, white bikini, all of which accentuate her figure. Since the video was released during the separation of Mottola and Carey, there was much speculation about whether the the theme of the video was linked to Carey's failed marriage. http://www.youtube.com/watch?v=w3KOowB4k_k&ob=av2n Whilst looking at the album cover it is clear that there has been a transformation as Mariah looks more glamorous and showing 'more flesh'. Unlike her other albums that just feature or mainly focus on her face. The effect of her 'blown hair' gives a more fierce and sexy look.
