9. Choose based on what doesn’t work
If you’re up for some trial and error and don’t mind redoing some failed manicures, this method will yield the widest array of shades. Choose shades you like and discard the ones that don’t work; it won’t take you long to figure it out. You can save some money by experimenting with department store samples. Just make sure you apply the trial shade generously; you really can’t tell much from one dot of polish.
