Nubar Twilight Kiss is a dusky light purple, and I think it's actually a pretty colour, and quite wearable to work. I kind of think it's one of those colours you can sneak into the office. Revlon Glimmer Gloss in Grapefruit Glimmer is definitely an office colour - it's a sheer pink with very fine, faint shimmer. Honestly, it's so sheer it probably won't look like much by itself. But I think Grapefruit Glimmer has a lot of potential over darker colours.
Here, I'm trying it out over a light colour, and I think it looks quite good. Just imagine the possibilities this one has with dark colours! In fact, I think that if you layer it over a dark grey-purple, you'd get a shimmer similar to Chanel Paradoxal. I mean, it does have that similar faint sort-of-pink shimmer, no? Not identical, but close enough, perhaps?
Application was pretty good for both - but then again I'm partial to Nubars and Revlons, they are some of my favourite brands. The brush size, shape, texture of the polish just works for me. Lasting power is average, these lasted for about 3-4 days before chipping, which is normal for me.
I like Twilight Kiss well enough, but I personally think Nubar has more exciting colours (like their awesome duochrome shades). Twilight Kiss by comparison is one of their more subdued shades, although it's still pretty. And Glimmer Gloss is a great work shade for someone looking for a slightly more interesting pink sheer. Not a bad combination altogether.
