Trunk - A wooden box, generally much larger than other kinds of luggage. Trunks come in smaller sizes as in the case of footlockers and larger ones called steamers. These days trunks are more commonly used for storage than transportation. Items large enough to require a trunk are now usually shipped in transport cases. Some of the better known trunk makers are Louis Vuitton, Goyard, Moynat, M. M. Secor and Leatheroid.
Suitcase - A general term that may refer to wheeled or non-wheeled luggage, as well as soft or hard side luggage.
Garment bag - A style of luggage that folds over on itself to allow long garments such as suits or dresses to be packed flat to avoid creasing. Garment bags come in both wheeled and non-wheeled models, and are usually one of the largest pieces in any set of luggage
