What is a suitcase?
Travel bag A sac de voyage is a medium- to large-sized travel or everyday bag with a flat, stable bottom and a distinctive rigid frame-clasp at the top. The term derives from the French phrase "sac de voyage," which literally translates as "travel bag."

The first travel bags appeared in the 19th century in the United States and were initially made from dense carpet fabrics (carpet bags). This allowed luggage to be made more cheaply as rail travel expanded. Later, durable genuine leather became the standard material for such bags.
From a utilitarian piece of luggage and professional attribute (such as a doctor's bag), the travel bag has transformed into an elegant urban accessory. Modern models retain the recognizable vintage shape while becoming more compact and lighter.
Distinctive features
The main feature of this travel bag is its rigid frame construction (clasp). The metal frame in the clasp area allows the bag to open wide and securely holds its voluminous trapezoidal or rectangular shape with slightly rounded top corners.

The base of the bag is always flat and reinforced. The bottom is often equipped with metal dowels that protect the material from abrasion when in contact with surfaces.
Traditionally, a travel bag has one or two short, sturdy handles, designed for carrying the accessory in the hand or under the elbow. Modern everyday models often feature a long, detachable strap for wearing over the shoulder.
What to combine with
In a business wardrobe, a strict leather satchel with a smooth texture in basic shades (black, cognac, burgundy) harmoniously complements classic trouser suits, pencil skirts, and strict double-breasted coats.

In a smart casual style, mid-size models in matte leather complement looks with straight jeans, cashmere turtlenecks, voluminous trench coats and leather loafers.

Tapestry-patterned textiles or distressed leather bags complement vintage and boho styles. They pair perfectly with midi dresses, chunky knit cardigans, fedoras, and lace-up ankle boots.
The bag's chunky shape plays well with contrasting textures. In eclectic outfits, the bag's sturdy frame accentuates the lightness of flowing fabrics like silk or chiffon.
