Special Occasional / wedding /white elephant / new years eve jumper / dress

I bought this from a boutique wedding gown shoppe for a New Years Eve party I didn't end up attending, no tags but never worn. Awesome sext pantsuit / jumper. Sequin and lace capped sleeves, flowing leg, polyester, but feels like saffron. Liked "cups" and zipper up the back. Prefect for wedding, Special Occasional, white elephant / new years eve party etc. Unfortunately I just don't go to enough fancy parties and I don't want it to just sit unseen in my closet! It says "large" but I am not sure why, I am sz 5 and loved it on me, I'd say MAYBE up to size 8.
