The dresser and the dressing table get confused constantly, and they are different pieces of furniture solving different problems. A dressing table is low, has a kneehole, and is used sitting down - it is for the slow business of hair and jewellery. A dresser is worktop height with no kneehole, used standing, and its mirror is wide rather than tall.
That width is the point. A tall narrow mirror shows you and nothing else; a wide one shows the room behind you, which is how you check what you are wearing against the light from the window, or see someone come in.
The stepped front is the other decision worth naming. A run of storage this long, built flat, reads as a wall of cupboard - so the centre section is brought forward and the ends returned, which breaks the length into three planes. Our master Indian artisans set those steps shallow, an inch or two, because the effect works by shadow rather than by depth and a bigger step would make the piece look assembled from parts.
