When it comes to birthday bashes, there are those for whom only tulle and tiaras will do.

If your wee one falls into the frilly set, look no further than the services of New York Princess Party.

Founder and entertainer extraordinaire Erin Shaw comes to your home or play space and creates a regal birthday soiree.

After choosing a princess (Cinderella and Snow White are faves), your little lady-in-waiting picks from a menu of activities like jewelry making, crown decorating, and interactive story time. Face painting, photo ops, and glittering goodie bags are included with every package.

Talk about the royal treatment.
