Hi everyone! I'm new around here (this is my second thread), and everyone was so helpful the first time I posted here that I'm back for more advice!

I fell absolutely in love with a Jim Hjelm dress, style JH8663. But its price tag is about $2,400 over my budget. Even preowned dresses sell for around $1,500, which is still very out of reach for my budget.

I contacted an Etsy seller about fashioning an affordable replica, but before I go down that road, I wanted to ask for advice on finding similar dresses for $600 or less.

I like the lace, the neckline, and the sleeve style most of all. Who has suggestions for similar dresses under $600?

Thanks!
