When making bags, you will see that people refer to a bag a clutch, shoulder bag, crossbody or backpack.
So far no surprises. But when they start to use names as bucket bag, hobo, sadle, satchel or sling, I have to think twice.
So what are all those different bags?
- Athletic bag: a soft, roomy bag used to carry sporting equipment and apparel to the gym.
- Backpack: a bag that is supported by the shoulders with double handles and lies across the back. Backpacks are supported on either one or both shoulders.
- Baguette Bag: A purse that is relatively long from side to side and small from top to bottom – basically a little like a baguette with a handle.
- Bowling Bag: A bag originally made to hold a bowling ball, this has become a fashion item.
- Bucket bag: roomy bag shaped like a bucket, usually has an open top and shoulder strap.
- Clutch Bag: Small but long bag (rectangular), evening bag without a handle. You have to clutch it – hence the name.
- Cosmetic case: bags of varying sizes and shapes with a zip closure lined to hold cosmetics.
- Doctor’s bag: A traditional doctor’s bag is a duffel-shaped leather satchel used primarily to carry small medical necessities when making house calls. The classic doctor’s bag is flat-bottomed with rounded sides, slightly elongated. Two large handles come together over the top for easy carrying. The mouth of the bag has a collapsible metal frame that springs open when handles are separated and tugged. The gaping mouth makes it easy to see into the bag and extract items.
- Duffel Bag: A large bag usually used for travel or sports. The name comes from Duffel, a town in Belgium where the thick cloth used to make the bag originated. Duffel bags are often used by sailors, and are sometimes called sea bags in this capacity.
- Envelope bag: a flat, square or rectangular bag with a triangle-shaped top flap that folds over like an envelope.
- Feed bag: bag that is used to feed an animal (such as a horse); covers the muzzle and fastens at the top of the head.
- Fold over clutch: a clutch with or without a handle that can be tucked or folded.
- Hobo Bag: a large crescent-shaped shoulder bag or any large bag that hangs from your shoulder and has a main compartment closure (unlike the “tote” which is normally open top).
- Messenger Bag: A bag with a long strap to be worn across the body that winds around the chest resting the bag on the lower back. Materials used in messenger bags are often more durable and water-resistant than traditional bags. Messenger bags are often used by bicycle messengers, though they are increasingly becoming an urban fashion icon.
- Minaudiere: a small evening bag embezzled with pieces of metal, semi precious stones or beads or covered with fabric or leather.
- Saddle Bag: a large bag (or pair of bags) hung over a saddle. Many designers use saddle bag as an inspiration for their designs. Therefore, their bags are called saddle bags, even though they are not actually saddle bag.
- Satchel: A structured handbag with double handles, locking hardware and a wide, flat bottom. May be large or small.
- Shoulder bag: any bag with a shoulder strap.
- Sling Bag: A bag with a long strap (similar to a messenger bag), yet smaller.
- Tote Bag: A medium to large bag with two straps. Sometimes sold as a reusable shopping bag, this bag can carry anything that is too large for a common handbag – also called a ‘Shopper’.
- Weekend Bag: A bag of a size to carry clothing and personal articles for a weekend trip.
- Wristlet – a clutch shaped bag that comes with an attached leather or bracelet-looking strap allowing you to hold your bag and dance freely.
