A wide bridal skirt from the side makes the spreading lower form and the area behind the wearer clear here. A noticeable headpiece belongs to the shown combination. This angle is useful when you want to compare the space occupied by the entire outfit rather than only front width. Small upper attachments cannot be reliably assessed from this view. Treat it primarily as a reference for the relationship between the rear fabric and your route.
Walk several steps in the actual dress, turn and stop. With your shoes, compare where fabric lies beside and behind you. Practise the action you would use to gather it along a narrow route. A workable arrival arrangement may differ from what you want for extended sitting. Discuss both before deciding only from an attractively spread shape.
Check the headpiece separately with your planned hair. If you prefer a veil, compare its rear area with the skirt. Request ordinary front and back views to complete the reference. A side picture helps with the space question; it establishes neither every upper connection nor material or a particular historical period.
