What style of dress is this one and where can I buy it (or a similar one at least)?

I tried various "search fashion by photo" but none of the matches looked similar to this exact dress. It is apparently vintage, brand La Belle from the 90s.

I'm trying to find a similar dress, please if you have any ideas/tips, share then. Thank you!
