A simple tank top is a type of garment that is typically worn as an undergarment or casual wear. It's a sleeveless shirt made from lightweight fabric, usually cotton, and features a straight fit with no collar or neckline other than a round or V-shaped opening at the front. The design of this garment is very basic and simple, hence its name, without any embellishments, ruffles, or additional details. It's perfect for layering or wearing on its own during warmer weather, providing comfort and breathability while keeping you cool.
