Solace London Rossi Halter Plunge V-Neck Wide Leg Jumpsuit Black Size 2-4?

Solace London Rossi Halter Plunge V-Neck Wide Leg Jumpsuit Black Size 2-4? Tag & Size are missing. I have included a picture of me wearing it for reference (last photo) I am a size 6. (5 foot 7 inches & 135 pounds) While I can get it on, it’s too snug. I would say it best fits a size 2-4. I also included measurements, please reference those before purchasing. Otherwise it is in very good condition! Absolutely stunning!
