A butter square neck tank top is a stylish and comfortable wardrobe staple characterized by its soft, buttery fabric that offers a luxurious feel against the skin. The square neckline adds a modern and flattering touch, creating a clean and structured silhouette. Typically sleeveless and fitted, this tank top is versatile enough to be dressed up or down, making it perfect for layering under blazers or wearing alone with jeans or skirts.
