I was quoted $290 for a 2012 chantilly (not sure in size... not a gm?) strap and the square hardware. And that’s just the strap. The vachetta around the curved bottom and the front strap with the buckle is extra, of course. If the canvas is flawless I’d go for it. Otherwise, no. But that’s just my opinion. Honestly, I’ve wished the strap on my chantilly was removable. You could just cut off the strap and use the canvas Pochette Métis LV strap, or fun bandolier straps, or a replica strap from mcraft leather on Etsy. I can personally vouch for that shop! The chantilly is a great classic bag!
