Manicurist here, very rare to have a client who matches fingers and toes anymore, with the exception of doing both french if you want the toes french. Many people will do french fingers and colored toes, but I have never done french toes with colored fingernails...go figure) It used to be the style to match colors, now it is an anything goes type of thing.
Most people can handle colors on their toes that they would never have on their hands, so I always suggest that people go with pedicure colors that they love but do not have the guts to have on their hands.
Above all else, have fun and enjoy the process! Very relaxing!
(and remember, if you want to leave with your own shoes on, it's best to bring flip flops, the kind where all of your toes are exposed. Also, I prefer to do the hands first because then they are good and dry before you leave, especially if you are driving.)
