Black suit trousers show several small folds above black lace-up shoes here. The open jacket reveals a white shirt, black tie and belt. One leg stands ahead of the other while both hands hang at the sides. The view follows the complete trouser line down to the shoes, making it possible to name the location of the lower folds. It does not establish an exact inseam or the cause of those folds from this pose alone.
If you wear a similar finish and want a change, begin with the same trousers and shoes. Set the waistband at its intended position. Then stand with both feet relaxed on the floor and compare the lower line again. Keep hands out of pockets to make the stance more consistent.
Show the proposed change at the appointment and request temporary pinning. Check the suggested length from the front, side and after several steps. This turns the visible folded area into a specific comparison for your trousers rather than an untested universal shortening rule.
