Long White Princess Mermaid Maxi Dress with Straps and Beaded back strap

Idk what this material is, but it’s soooo beautiful and iridescent in the sun. It feels mermaid coded when it catches the light. Very cool and light feeling fabric. NEVER WORN. I saw it and thought it was cute, has tags still. The beading in the back was the reason I bought it. Super cute and princess like. It says size 9, but I believe it’s realistically more like 7-9! I am a size small and cannot fit it and too lazy to get it tailored, if you’re a size M-L this may be for you
