To make achieving a straight line a bit easier you can try applying a piece of tape to the nail before the neon coat. Just be sure to let the nude base dry for at least 30-40 minutes or more first! I am especially loving this neon and nude combo right now because it's great for (finally!) making the transition into the warmer months.
