My advice is to be playful and trust your instincts. Finding that special hat should be a fun and memorable experience. You should feel comfortable and at ease.

Above all else, enjoy yourself!

Enjoy the experience of choosing a hat, or the wonderful deluxe experience of having a bespoke one made for your outfit. Enjoy the day of the event and then keep the hat as a memento of the party. Store it away until the next time you have a chance to wear it and you can open the box and feel like you are meeting an old friend.
