Found my dream dress, now I need shoes!

Somehow I lucked into a nearly perfect 1970s vintage wedding gown this has all the elements I love and is damn near my exact measurements. I need to have it slightly altered so before I do that I want to find my wedding shoes so I can have it hemmed if need be.

I’m envisioning a pair of low block heels with some pretty embroidery. I found tons of gorgeous ones on Etsy but way outside my budget. My dress was $98 on eBay, I can’t imagine wearing $300 shoes with it.

I’d love to find a pair second hand, since the unintentional theme of our wedding is “nearly new” at this point 😄

Any ideas on where to find gently used shoes like this? Or ideas for other styles for this dress?
