First I did two coats of white as my base.
I used a dotting tool to mark the center of my nail.
I then used the same dotting tool to create 4 dots along the sides of the center dot and blended together to create the bow.If you want you can also create a bow with a straight edge here.
I then painted the black french tip.I did not do it here but it also looks good if you paint a black V shape tip to create the look of a suite jacket instead of the rounded tip.
I then used a smaller dotting tool and created the center button first tho center then the top and bottom. Let dry for a minute then use your top coat and ta-dah you have fancy tux nails!
