Armoires are French wardrobes, free-standing pieces that were usually made for folded clothes and linen, i.e. with shelves rather than rails.
As with any wardrobe, they come in many sizes, depths and heights, woods, finishes and colours. There is often a central drawer for small items and valuables
In many traditions and cultures large cupboards were wedding gifts; and young girls spent much time preparing their household linen trousseau in readiness for marriage. Armoires are often referred to as marriage cupboards and if so may well have some sort of carving or plate to signify.
