Princess Beatrice's Royal Wedding Hat Gets Attacked on Facebook

The Philip Treacy hat that Princess Beatrice wore to the royal wedding Friday is being mocked endlessly online.

"I think it's actually a uterus and fallopian tubes," joked one member of the tan hat with a swirling bow. (Her matching dress was Valentino Haute Couture.)

"In the church. It was like the devil peering over the Queen's shoulder. Scary really," joked another. PHOTOS: Kate Middleton and Prince William say "I Do"

"She looked like a creature from Dr Who," wrote another.

One site noted her dress and matching coat were "elegant, but her headpiece was deemed to be a ludicrous addition, perching on her forehead at an impossible angle and detracting from her sophisticated outfit." PHOTOS: Famous royal weddings

Not everyone hated on Beatrice's hat.

"Yes, Beatrice's hat certainly deserves a Wall of It's own, but there were lots of great Runner-ups in the crowd too....let's not leave them out either. British women are gutsy...I take my hat off to them!! :D," wrote one fan on Facebook. PHOTOS: The 9 wackiest wedding celebrations

Treacy created 36 hats for the royal wedding, including for Camilla, the Duchess of  Cornwall, Princess Eugenie, Princess Michael of Kent, Queen Anna-Marie of Greece, Victoria Beckham and Princess Mathilde of Belgium.
