I just got this at Saks. I am borrowing the pic from Mon though (hope you don't mind). It fits as a belt too.
I bought this one as well as a few members on the forum. I don't know if they are still available, but you can check-
They come in white like I have and black. And each color comes in two sizes/lenghts
I have this in white as well. It comes in black too. Style number is A26978YO2019 and it comes like 5 sizes, starts at 75 and goes up to 100, depending on your waist size and or wear you like to wear your belt. I wear my belts lower on the hips so I get a size bigger. The SA can help you find the right size. Good luck
The 90 will be perfect for you. Big around the waist, but nice on the hips and great for the necklace part. congrats. Did you get white or black?
