I think there's something so classy about a half-moon mani and when you combine it with a classic red it's utter sophistication in my opinion. MAC Sherille is the perfect red.
The half-moon is easy to create using paper re-enforcers or a steady hand, if you have one. I do not.
What I especially love about the half-moon is that you don't have to worry about messing up around your cuticles :P
I made the above nails festive by dotting on some gold polish - China Glaze Ultamate Holiday. Even then it's not explicitly festive so these nails could definitely be worn throughout the year. They remind me a little of Lana's from a while back.
