This is a MUST for your capsule wardrobe. It is super stretchy, 3/4 sleeve, flattering V-neck, thick enough to not be see-through, but thin enough to give you a sleek silhouette. You can put a multitude of colors under the sweater for any outfit, or wear it alone for a sexy neckline. It’s one size because it’s super stretchy and a thick weave. Prob a generous medium size. I bought this at a little boutique in a northern Michigan town. Model has slightly different style- but I wanted to show how the V neckline looks and how form-fitting it lays on the body. Best thing!?!? It’s 100% made in the USA!! Buy local!! 🇺🇸
