The top three of 2023 were;
Working out the winner was difficult.
Orbit was the first to go, it isn't massively unique to my collection. I do like it though, just similar but a bit different ILNP Eclipse but grey rather than black.
In second place Cold Weather Blues, I think this came second because of it being a thermal and the pigment doesn't last forever in those. It is a white to blue thermal with hex, micro and snowflake glitters.
Which means the 2023 new to my collection polish is, How Polarizing. As this is magnetic there isn't a shelf life to it which means I can enjoy it as is for as long as I have it. Its a navy magnetic polish with scattered holo particles.
