Since I was playing with these two jellies and layering, I decided to try them out by themselves, without glitter. I applied three coats of Paloma, then two of Frida, and one more of Paloma to get this look:
I actually kind of like how these look together. It almost makes me wonder if Zoya didn't just mix these two to come up with Katherine!
I haven't yet gotten Katherine, but from swatches I've seen, it looks pretty similar to this, I think!
