Armani Sheer lipsticks (also called Sheer/Transparent, not to be confused with Shine or Silk lipsticks) are $25 each. If the names weren’t confusing enough, the lipsticks are also numbered (not in any logical order). I also find the Armani website somewhat confusing — depending how you navigate there, you may find yourself on a product page with no pricing information.
According to Armani’s website, the currently available Sheer colors are 0, 2, 5, 6, 8, 9, 10, 11, 14, 21, 24. (So in these photos, 2, 9, and 21 have not been swatched. And though I swatched them, 4, 18, 19, and 29 may not be available near you.)
