NWOT Shy Girl Long Sleeved LBD (see notes on size)

Been sitting in my closet for years, never worn. A little too low cut for work (at my job anyway) and I don’t go out enough to wear it for an event. Nice thick and soft material. Flattering cut. Size is L but I think it fits more like a medium. For reference I am a small/xs and this is just a little big on me. Not sure how the brand normally runs. It has some stretch so it could fit multiple sizes. Small-medium for a more modest fit, med-large if you want curve-hugging. 🙂 Questions welcome
