For the herringbone nails (I keep calling them herringbone because I'm like 90% sure that's actually what the pattern is called?!) I followed this awesome tutorial which calls them chevrons. I was surprised by how easy it was, especially broken down into easy-to-follow steps! You'll definitely need a dainty striper brush to get the job done, tho.
My ring and pinkie (and thumb!) nails are all just 1 amazinggggg coat of Cult Nails Fetish with some straight-across half moons done with tape. Super simple and quick, the sort of detail I adore in person (and can never get to photograph correctly, but c'est la vie!). This was my first time using Fetish and I was soo impressed with it; opaque in one coat, great formula (other similar polishes can really drag, because the polish seems to start 'setting' once it hits the nail), and quick drying. I managed to do those tape accents like 20 minutes after painting, no fast dry top coat required!
Overall I am really happy with this look :) Now check out the other black and white nails for today below!
