Comfortable, sexy, long sleeve sweater dress

Worn only once and now is too small, it has long sleeves and is perfect for a fall date night. Cute material rushing on the bottom so it hides the belly. The size says L but it’s a small dress, I’m a size 6 and it’s too tight on me which is why I listed it as a S. It’s from a boutique. Let me know if you want measurements or have questions!
