wear it with a dash of disdain and wit
I’m trying not to shop.

So visiting Shrimpton Couture online was a mistake. Just look at this necklace designed by stylist and “fancy maker” The Glamourai.
The best word for it is gratuitous. I say that approvingly - rich and whimsical and luxurious and unnecessary in the best way.
Naturally it is sold out. But you can see more luxury re-worked vintage and couture at Shrimptom Couture.
