The advertisement for the perfume featured a cartoon Katy Perry battling in a mideaval setting. 
Oh So Sheer opens with wild berries (including mulberry, elderberry and blackberry), and dark plum. Its heart is composed of velvet red flower, lilac, freesia and rainbow plumaria, while its base notes are cashmeran, liquid praline and patchouli.
A limited edition EP was also released with the perfume which included remixes of tracks from Katy's album Prism. The EP was released as a CD which when inserted to a computer, directs you to a site in which you can download the remixes. All files are MP3 data files.
