A spread skirt with a visible leg opening defines this side view. The wearer stands sideways, one leg is clearly visible and the pale skirt spreads behind her. The bodice has a patterned surface and a tie is visible at the waist. The pose helps compare covered and open areas, but it does not show how the skirt falls without arrangement. Neither a particular lightness nor a fibre composition can be confirmed from it.
Use the view to ask about the behaviour of the actual skirt sections. Walk normally and stop before anyone spreads the fabric for a picture. Check the leg opening while sitting and stepping onto a stair as well. If the waist tie interests you, ask how it closes on the offered model and whether it is decorative or has another structural purpose. The photograph alone does not answer that. Add a clear front view in a relaxed stance, then compare the skirt with the shoes and routes you plan to use.
