Need a fun D-I-Y idea for Halloween? Try Princess Beatrice’s royal fascinator! Here's how to make it in three easy steps:

WHAT YOU'LL NEED:2 metal headbands, wired pink ribbon, glue gun (all available at M&J Trimming, 212-204-9595).

HOW TO:1. Stack two metal headbands, with bottom ends of one on curve of the other, and glue them together.

2. Wrap wired ribbon around top headband until completely covered; glue down both ends.

3. Create two bows (leave ends hanging) and secure both to top of headband by wrapping a piece of ribbon around knots three times and gluing end down.

COMPLETE YOUR LOOK:Rim your eyes in black, don a pastel day suit, and slip on this haute couture headgear!
