3 of them below are my favouite O.P.I nail colours.
#NLR39 very natural light pink, #NLW42 bloody dark red close to black & #NLC22 cool silver. (From left to right)
But before I apply any nail polish, I will apply "O.P.I Natural Nail Base Coat" #NTT10 (Right) to protect my nails. And I will apply "Korea Mainstream Diana Manicure" #03 transparent (Left) or #06 nude (Centre) as a top coat.
And I love to put some accessories, I really enjoy it. But sometimes I just put the base coat & top coat which is a must. :p
