Waist openings and necklines place exposed space in different locations in this gallery. The first dress has a visible opening at the side middle. Its front fabric also runs high towards the neck, while the skirt opens at the leg. Those three features can be described separately. This makes it easier to decide which area you want open on a real dress rather than treating every exposed line as the same arrangement.
The one-sleeved version moves upper contrast to the shoulders and directs side folds towards a diagonal skirt opening. The patterned gown shows exposed shoulder space beside larger side sleeves. The blue look emphasises a V-neck, narrow waist and open leg area with an inner surface visible. None needs to be called another waist cut-out to make a useful contribution to the comparison.
Choose the intended location first at a fitting, then its relationship with the rest of the dress. Compare the outline standing normally, reaching and seated. Request actual rear views and inner layers where they matter to the chosen opening. The pictures help separate different preferences for exposed space so the real garment can answer a clearly stated question.
