The long pink ball gown shows a closer floral bodice above a very broad skirt. Its upper front edge dips towards the centre. Translucent-looking decorated arm areas cover the upper arms and part of the forearms, widening at their edges before reaching the hands. Longer floral outer borders run diagonally across larger less decorated skirt areas. One hand rests at the waist and the other lower beside the fabric. The broad lower finish reaches the floor and conceals the shoes.
This view is especially useful for deciding how early you want substantial width below the waist. Separate that preference from the pink colour and floral pattern. Visible fullness does not explain an inner support or a particular number of underlying layers. The diagonal borders do not establish a removable outer section either.
Ask to see a similar candidate straight on with relaxed arms and from the back in full. Check the lower length with your actual shoes. If the large less decorated area is your main interest, record it separately before comparing further decoration or a different sleeve frame.
