trousseau (n.)

"a bride's clothing, etc., brought from her former home," 1817, from French trousseau, originally "a bundle," diminutive of Old French trousse "bundle" (see truss (n.)). Italicized as foreign at first, nativized by 1833. The Old French word was borrowed into Middle English early 13c. as "a bundle of keys," but it fell from use.
