The term 'roomy dress style' can be summarized by two crossword solutions: ALINE (5 letters) and TENT (4 letters). An ALINE dress is a type of dress that is fitted at the top and gradually flares out from the waist down, creating a silhouette that is roomy and comfortable. A TENT dress is a type of dress that is loose-fitting and hangs straight down from the shoulders, creating a roomy and relaxed look. Both styles are popular for their comfort and ease of movement.
