Looks like Stephanie Baden may have gone hat shopping with Lady Nicholas Windsor ahead of today's wedding, hm?  I like Steph's navy blue version of the fascinator about ten times better than Paola's.  The coat, however -- we may need to talk.

The other necessary topic of conversation here?  Our photo interloper, the lovely Princess Sibilla of Luxembourg, who looks like she's sharing secret messages with the photographer.  But, Sibylla -- where is your hat????

Let's start our evening of Tiara Alerts with a brand new princess, shall we?  This is Stephanie, the Hereditary Princess of Baden.  Her husband, Bernhard -- that's him on the right -- is the son of the Margrave and Margravine of Baden (which makes him a cousin to the British royals through the Margrave's uncle, Prince Philip).

Stephanie's brought out a Baden family heirloom tiara for the evening, too -- it's the Baden Sunburst Tiara.  The tiara is made up of a series of sunburst brooches that I believe can be worn individually.  Love seeing obscure royals in obscure tiaras, but this one's not my favorite -- it's like a cousin of the button tiara, and you all know how I feel about those, LOL!
