Experts' Expert: Philip Treacy, world's greatest hat designer, on wearing a "Statement Hat"

Said Treacy — who designed Princess Beatrice's memorable chapeau (above) for William and Kate's wedding — about striking hats, "I love that they agitate the wearer and the viewer."

Precisely what I'm about in the virtual space.

But I digress.

From yesterday's Wall Street Journal, a few tips from Treacy on how to use it:

• If you're wearing a statement hat, don't wear a statement dress

• The hat should not match the wearer's shoes and bag

• If you're very tall, you can make a very large hat look small

• Even large hats should be light

• Put your hair up when wearing a hat "because it shows off your neck" and creates a more elegant line

• Don't take your hat off during an event, even a church service. "It's like going somewhere and taking your underwear off."

I like that.

As Treacy remarked, "Sometimes your hair isn't enough."
