Vintage No Boundaries Dress

I wish this fit me—really cute with a shirt under & tights, oxfords or tall boots. Would best fit a large—I’m a size 6 & 5’7, it comes to mid thigh on me. Bought from a curated shop & tried to make it work but wore 2-3 times. Great condition with no flaws. Also has a small slit at the front. Juniors size 11-12 but I would say it best fits around size 10.
