Yeah I thought so too when I wrote my comment about it. It's kind of a cute look though, if you take the politics out of it.
But nail salons are not common in Sweden (it's an American - Anglo thing) and you couldn't do that yourself..
From the look of Emma Tregaro's nails she simply used some nail polish she had at home.
Since she was hellbent on doing it, she might as well have done it with style. There's probably an American style nail salon somewhere in Moscow that she could have gone to, to do it properly.
