We love how subtle yet unique this cool trend is. It works best on longer nails (so you can actually see the color under your tips). If you think it’s not that noticeable, you’ll be surprised. It’s a great way to catch the attention of your colleague sitting next to you at work or the person behind the cash register (trust us, they will notice).

First, paint your nails with a strong, dominant color — we used a gorgeous fuschia. And then paint the underside of the nail with a contrasting color (we thought blue worked well in our case) If your nails are on the shorter side, you can “fake it” with artificial nails that already have polish on the underside, like Broadway Nails French Flip Nail Kit, $5.49.
