If you're into a more sheer pink, my favourite is I Theodora You, also from OPI.
If you're into textured polishes, OPI's Liquid Sand in Magazine Cover Mouse is a pretty red with a gold shimmer.
A classic hot pink that I love is Kiss Me On My Tulips. Or if you're more of a lavender girl, you can't go past Lucky Lucky Lavender.
Another beautiful hot pink, with a purple undertone is Flirt by piCture pOlish (appropriate name for V-Day! ;)). This one also has a flawless formula. You can get away with just one coat!
February is summer time here in Aussieland, so I had to include a nice neon pink. My favourite is Bottoms Up by China Glaze. The formula on this one is less than perfect, so it will take a bit of patience, but the end result is awesome.
A classic bright red option is Ever Reddy by Covergirl, from the Outlast Stay Brilliant line. This one is available pretty much everywhere. It has a jelly-ish sort of finish.
For the glitter gals! Ulta3 Disco Fever is a great red glitter that's pretty easy to find, and only $2! It would look cute over any of the light pink polishes I mentioned above, or a red.
Haley Good Lookin' is a pretty rosy pink glitter from Nicole by OPI. NOPI is now available at most Target and Woolworths stores here in Australia, so it's fairly easy to get your hands on, if you come across a well stocked stand! This would go well over any colour, really. It has great coverage with just one coat, also.
If you prefer a purple look, China Glaze's Put a Bow On It from the 2013 Holiday collection is a nice full coverage glitter.
