A fitted square neck bodysuit uses both the neckline and the close fit to create definition through the chest and torso. The square neck broadens the shoulder line and the fitted cut creates shape at the waist and through the body which combines to create a flattering silhouette for many proportions. These bodysuits are not loose or forgiving which means they need to fit properly but when they do the effect is genuinely transformative. They work well under looser pieces where you want your shape to be clear or worn alone when you want the full benefit of what fitted cutting can do for proportion.
