I picked this bottle up at a recent trip to Meijer. I've seen some people swatching it and liked the uniqueness of the color. As you may (or may not) know, Studio M is marketed by the same company that produces Color Club polishes, hence the identical name and color.
So, anyway - I thought it looked unique. But as you'll see in the comparison shots below - it's not really that unique at all! :)
You can't really tell by looking at the bottle or nail pictures, but Nouveau Vintage is actually gold and greenish glitter in a RED base. Check out the neck of the bottle while you're applying it, you will see the hint of red. You can't see the red base once it dries. I think I applied 2 coats and coverage was good. It's a nice antique brass-y looking shimmer and a good fall color.
Now, on to the comparison photos. I compared this color with others from my stash.
Left to Right Studio M Nouveau Vintage, Nina Ultra Pro Mossy Britches, Revlon Insta Dri Bronze Ablaze and Butter London Wallis. The closest match is the Sally Hansen Bronze Ablaze. Mossy Britches and Wallis have a lot more olive in them with Wallis being more shimmery than the other swatches. Can you see the hint of red in this comparison shot?
Nouveau Vintage, Mossy Britches
Bronze Ablaze, Wallis
So my final verdict is that if you already have one of the other shades pictured, you can pass on this color. They are not dupes, but close enough that only another nail blogger could see any difference in color among them.
