As I mentioned in my Chanel Summer 2016 post, Chanel in #518 Chaîne Or - released as part of the permanent collection this spring - seems to have disappeared from all online retailers except Saks Fifth Avenue. I don't know whether it has been phased out of the permanent line, or there is a production delay or something and it will be re-stocked. So if you want to be safe, it's time to snatch it up now.
Chaîne Or is a pretty standard yellow gold metallic with subtle shimmers that catch the light. It does show some brushstrokes (although not horrific), so I did 2 thin coats and sponged on a third. I think that third coat is necessary however you apply this polish, otherwise you can get some sheerer patches. The formula - apart from the brushstrokes - is very good. Not particularly special, and it isn't a travesty if it's been pulled from the permanent collection, but a solid, well-performing polish.
I have been slowly picking up the re-launched Le Vernis line, and so far so good. Sabrina at The Beauty Look Book has a more thorough rundown comparing the differences between the new and old lines (the brush is wider but still traditionally shaped, and she found the lasting power improved). I haven't fully tested for wear, but I have never had problems with chipping from my Chanel polishes, and that remains true for the new line, which is marketed as Longwear Nail Colour. I like the brush quite a bit and thing most people will welcome the change: for patchier shades especially, it helps with application, and I don't have trouble maneuvering the brush around my cuticles. I had one issue with the brush for #536 Émeraude, where the bristles wouldn't spread out fully when I put pressure on them. This meant I had to do a bit of cleanup to get close to my cuticles, but I haven't experienced that issue for any of the other new polishes. For those concerned about chemical formulas, these new polishes are 5-free.
