Indian Spice!

Posh got her sari on in a photo shoot for Vogue India ... she donned a traditional Indian bridal costume for the November issue of the mag.

No big revelations in the accompanying article -- she says she's a fashion risk-taker and called the Indian look "so me."

The real revelation here is her hair! Remember the good 'ol days with extensions?! Really, I love Posh either way -- softer and cute with long hair or hot and edgy with the pixie 'do -- both are great!
