If you are fat, your neck will appear shorter. Sweaters and underwear are not suitable for wearing turtlenecks. Of course, V-neck and low-neck, exposing part of the neck, make the neck look longer, so V-neck and low-neck clothes are the first choice for overweight boys. If someone wears a low-necked sweater in winter and is afraid of the cold, it is fashionable to wear a scarf with good texture.
