Now a post for Elephant's Child .
She is under the impression that's she's too large to wear a tiara (I bet my bum is bigger than yours) so here's Maria Theresa of Luxembourg wearing some serious bling. She's not so tall but a little broad across the beam and she carries off this many diamonds like a champ. The Luxembourg Empire Tiara, not for the small and timid.
Although if you're just popping down to the corner store for a coffee and muffin, this smaller bandeau of rubies and diamonds would be quite in order. Just make sure the thongs match and you're wearing gloves.
