ISO cinq Louise dress or similar for October 2026

Hi! I am in search of the cinq Louise dress for October of 2026. I would love to purchase from another bride. I’ve tried it on in store and fell in love with her but it’s a little out of budget. I’m a street size 4/6.

Additionally, if that option doesn’t work out I’m looking for some cool designers to look into. I love a basque waist or anything similar that really snatches you up and has gorgeous fabric.

Thank you!
