In my salon we use,O.P.I, Orly, Jessica, China Glaze,you wiil use a mix off white and pink hues to do french polish.
Bright white,milky white,pearly white...then peachy pink,clear,nude pink,shimmer pink.american,list goes on...all depends on clients needs.
To start go with O.P.I Allpine snow(white) when you can do perfect smile line with this...you can use any white,for the pink bubble bath(pink),passion(peachy pink),catch the garter (shimmer pink)nice for weddings.you will soon add others,but hink this is a good start.good luck
