I need help recreating this look for an event. All I know so far is that these are hand sewn on. Any ideas on cheap alternatives to the suit and especially the gems/stones on it. ANY advice is helpful.

I have NEVER recreated an outfit but I want to recreate this one SO badly!

Here’s a link to the original designer making it themselves: https://www.instagram.com/p/DJUW6l5tGO_/?utm_source=ig_web_copy_link&igsh=MzRlODBiNWFlZA==
