I'm pretty late posting this - but this is what I did for Valentine's Day:
We don't celebrate Valentine's Day - both TheHusband and I feel that romance should be spontaneous, not expected.
But It's a good excuse to do fun nail art, so yay!
Thumb, middle and Pinky finger all started with a base of Sinful Colors Snow Me White. Over top of that, I added two coats of Sally Hansen Digital (from their HD line from a few years ago). Digital is, as you can see, a hot pink. It's fully of shimmery frosty goodness. I'm not a big pink person, I was actually planning on using red for this manicure, but I hadn't used Digital yet, and I thought I should.
On my thumb, I used a dotting tool to create a pattern (from an image I saw on Reddit), and applied a gold heart charm.
On my middle finger, I used my trusty Claire's striping polishes to add racing stripes down the side of my nail.
On my pinky, I added random dots using a dotting tool - first in black, and then white over top.
For my index and ring fingers, I started with a base of OPI Black Onyx.
On my index finger, I applied a coat of Claire's High Maintenance - a mini polish that is a fuchsia jelly base filled with fuchsia glitter.
Finally, on my middle finger, I created a french tip using Sinful Colors Snow Me White, then applied two coats of Sally Hansen Digital. I cleaned up the line using the Claire's white striper, and applied a black heart jewel.
It was a bit time consuming (and I actually redid my middle finger - I had it completely different, but it didn't fit in at all), but I liked it for a couple of days :)
