Helpful Information

Is an open-back gown supportive enough for dancing and movement?

Yes—this gown uses strategically placed straps and a fitted sequin fabric that provides secure hold across the torso while keeping the back open for dramatic effect.

Does the sequin fabric stretch or feel restrictive?

While the sequins create a structured surface, the underlying fabric has slight flexibility, allowing comfortable movement without losing the sleek, sculpted look.
