For anyone who likes a soft pastel blue manicure. OPI's own copy says pastel blue is not just for baby boys, so it is aimed at a broad audience of home users and nail technicians alike. Using it needs nothing beyond a base coat, two thin coats and a top coat.

Soft pastel blue is a classic that never quite goes out of style, and It's a Boy! is a well-known example from OPI's range. OPI describes a smooth, glossy finish with brilliant shine, and the application routine of two thin coats brushed along the free edge is designed to help it wear without chipping at the tip.

1. Prepare the nails properly, then apply one coat of OPI Natural Nail Base Coat.
2. Apply two thin coats of color to each nail, brushing the formula along the free edge to help prevent chipping.
3. Finish with OPI Top Coat, capping the free edge.
4. For faster drying, add one drop of OPI DripDry Lacquer Drying Drops per nail.

Pastel blue is a shade many people find easy to wear, and OPI describes the finish as smooth and glossy with brilliant shine. The instructions to brush color along the free edge and cap it with top coat are aimed at reducing tip wear.

On the other side, light pastel polishes show streaks and uneven coverage more readily than dark shades, which is why two thin coats are recommended rather than one thick one. Like any solvent-based lacquer, it thickens over time and should be kept tightly closed.
