The sweater that is most suitable for fat girls on the upper body is a V-neck sweater, which lengthens the lines of the neck, so that overskirt will not look so bloated, but also show exquisite lines and be super slim. A white V-neck sweater like this, with a black coat and a pair of casual jeans and small white shoes. The shape is concise and neat without losing the sense of fashion.
