and Zoya Cinnamon, as an example or two.
It'd be fun to do nail wheel or two with all of these on it, if I can manage to get them all together.
Note that I don't limit myself to polishes that were released in the last year. They just have to be new to me, not brand-new. Several of these have been around for several years, but I'm just now getting around to trying them.
Anyway, my favorite will probably come off this list, and I'll probably do a top ten from this as well. (Things that I left off this list are still technically eligible if they were new-to-me this year, but I think the chance that I'll swoop back in and pick something else is awfully slight. I have not actually decided on a favorite just yet, though!)
It's interesting to me that there are so many Pretty Serious polishes here. I also see two from the RBL+R29 collection. And several heavy-duty flakies made this list, from various brands.
