China Glaze Altered Reality Nail Lacquer ($8.00 MSRP for 0.50 fl. oz.) includes six shades of color-changing shades. I’m not aware of any other polishes that change color with the addition of a top coat, so none of these have dupes.
MAC Pro Longwear Eyeliner ($19.50 for 0.04 oz.) is a new formula that has launched with Apres Chic, which is limited edition as far as I know–but they are not marked as limited edition on MAC’s website. The new formula is available five shades: Black Ice (rich black), Mountain Air (vibrant teal), Night Trail (deep navy blue), Rich Experience (true brown), and Snow Shadow (purple violet).
NARS Night Series Eyeshadow Palette ($55.00 for 0.31 oz.) was a limited edition eyeshadow palette that included six of the Night series eyeshadows: Night Star (sheer peach shadow with pearls), Night Clubbing (black with pearls), Night Porter (black with green pearls), Night Rider (soft plum with glitter), Night Flight (black with cobalt pearls), and Night Breed (black with glitter).
MAC Fabulousness / Smoky Eye Palette ($39.50 for 0.14 oz.) contains five eyeshadows: Taupeless (lavender pink), Satin Taupe (taupe with silver shimmer), Love Spice (mid-tone rosy pink with pearl), Spellcaster (matte aubergine), and Black Slip (rich blackened plum with pearl).
Dior Diorling Diorific Vernis ($26.00 for 0.40 fl. oz.) is a sheer, shimmering champagne gold with flecks of copper-red. I’m pretty sure this is a renamed version of Golden Light (also known as Golden Era and or Lumiere or #207), and while it may be called Diorling, the number is #207. China Glaze Jingle Bells has a similar coloring, but it’s opaque and does not have any red shimmer/sparkle. Chanel Diwali is more of an antique gold (less yellow). OCC Cruising is a stronger yellow gold and has a lot more shimmer/glitter. Readers mentioned some great dupe potentials here as well!
