Sexy high end little black dress

LITA brand. High end couture brand with ready to wear line. Ribbed short sleeve. Collared and v neck. This is SEXY on. But smooths out at the same time. Not your thing cheap body con. You'll feel like a million bucks in this. Would fit L-XL well. I'm a medium and was hoping for a slightly looser fit. It looked amazing but I could tell it would look better on someone truly its size.
