If you’re in doubt about your next manicure, try coffin nails. This stylish nail shape is a staple in the manicure world and won’t go out of style anytime soon. The best thing about coffin nails is that they can flatter almost any hand shape and be twisted into any style you want. They are bold and dramatic, but not as sharp as stiletto nails, and are long and wide enough to pull off the prettiest nail designs.
