First apply your basecoat.
Once your basecoat is dry, apply your basecolor.I'm using a dusty gray purple from color club
Now Gather your materials for the design.If you don't have dotting tools you could always use a bobby pin,toothpick,or even the back of a paintbrush
Take your black & make dots close to your cuticle & half way down your nail
Do the same with the white,but make the dots closer to the tip of your nail
Repeat to all of your nails then apply your topcoat & your design is finished!
