"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
