Why not try another bag? I'm not all that familiar with stock and prices, but I know the Artois PM in classic colors is also under $1700, and it's more unique than the St. Louis. To be honest, in NYC I see as many St Louis as I do Neverfulls. I only mention this because you say you like the unique look
I have never seen anyone carrying anything besides the St Louis though! My mom uses her Artois every day and the corners are a little scuffed, but the leather on the handles is still absolutely beautiful. Whatever you buy, you're spending a lot of money on something for YOU! If you love the St Louis, that's what matters more than anything else! If you just would like a piece from Goyard, there might be a couple options! If you can stop by a Goyard store the SAs will definitely try to talk to you, but you can look around because all the prices are displayed
Good luck! Can't wait to see what you get!
