Ciate Advent Calendar Day 19: Underwear Base Coat

Only a few more days to go until Christmas woop woop!:) Todays treat from my Ciate Advent Calendar is their Underwear Base Coat. I have never tried this before so it will be interesting to see how I find it! It's really cool that they have included a top and base coat in the calendar this year. Maybe Ciate will manage to get us to convert to using their top and base coats regularly.

Have you ever tried Ciate's Underwear Base Coat? What did you think of it?
