A waistless dress is a type of garment that does not have a defined waistline. It can be made in three different styles: TENT, ALINE, and SHIFT. A TENT dress is a loose-fitting garment with a straight silhouette that hangs from the shoulders. An ALINE dress is a dress that is fitted at the top and flares out at the bottom. A SHIFT dress is a straight, loose-fitting dress that falls straight down from the shoulders. All three styles of waistless dress are comfortable and stylish options for any occasion.
