Here was what I wore for Pippa McManus' exhibition opening night (post here). It's a very simple outfit, which reminds me that I should show you what I've managed to reduce my wardrobe to post-cull!
The large agate slice is similar to the one S has - we went on an internet shopping rampage over exams, which resulted in many recent acquisitions including this. It's solidly crafted out of a polished slice of Brazilian agate, and to be honest, wearing it makes you feel like a total winner since it has the weight a medal. We've dubbed it our "medallions of power". Insert enthusiastic fist pumps and exaggerated consonants.
