NARS Adelaide Illuminator ($30 for 1.1 oz/30ml) has been on my radar for several months. I saw some sneak peeks on Specktra and almost died of excitement when I found out there would be a shimmery pink highlighter. Adelaide is currently exclusive to Nordstrom with an official release date of February 1st. As many others have noted, Adelaide is a very shimmery pink and almost glittery. I usually do not like glitter on the cheeks but this illuminator is almost like a grown-up version of glitter. I have to use sparingly and swipe it lightly over powder blush to give a highlight. I found it lasted all day over a powder blush - right now my skin is normal but slightly dry. There was no shimmer or glitter fall-out. It stayed put on the skin from morning to night. If you don't like any sign of glitter on the cheeks you may want to try Giorgio Armani Fluid Sheer #8 instead which is similar but paler in color (scroll down for swatches).
Swatched below you can see that Adelaide blends out to a cool sparkly pink on my olive skin. For me it's pigmented enough to wear as a very soft blush but I prefer to layer over a powder blush with a very light layer.
Here is Adelaide blended and sheered out with a foundation brush:
As others have noted, the shimmer and glitters are noticeable. I half love it. I tested during the work week for multiple days. Half of the testing days I felt it was too over the top, while the other half I thought it was subtle enough for the office. I recommend testing before buying if you're unsure about the shimmer. On my olive skin it shows up and brightens the skin with the combination of pink and silver glitter shimmers. Perhaps I just need to be braver with shimmer and sparkles sometimes.
