A Sporran is a pouch (the word is simply the Scottish Gaelic for 'purse'), now a decorative part of Highland dress but originally an everyday practical item, made of leather or fur, usually with more or less elaborate silver or other ornamentation, especially on the clasp or hanger. It is worn on a chain or belt around the waist, allowing the sporran to lie below the waist of the person wearing a kilt. Since the traditional kilt does not have pockets, the sporran serves as a wallet and container for any other necessary personal items (such as a hip-flask). It is essentially a survival of the common European medieval belt-pouch, superceded elsewhere as clothing came to have pockets, but continuing in the Scottish Highlands because of the lack of these accessories in traditional dress. The sporran also protects a person's decency. This was originally because the ancient 'great plaid' (Gaelic breacan an fhèilidh), formed of a long draped cloth, had a gap at the front, and in more modern times because the kilt is traditionally worn without undergarments. Historically, the sporran was used to carry a day's rations. Some believe it served as armour for a vulnerable area of the body.

• "Day Sporrans" are usually simple brown or black leather pouches with little adornment. These "day" sporrans often have three leather tassels and some Celtic knots embossed in the leather. Traditionalists prefer brown or buff colored sporrans, belts, and shoes for day wear.

• "Dress Sporrans" are larger than the day variety, and are more ornate. Victorian examples were often ostentatious, and very different from the simple leather pouch of the 17th or 18th centuries. They usually have chrome or silver cantles trimming the top of the pouch and a fur covered face with fur or hair tassels. The cantle may contain intricate filigree or etchings of Celtic knots. The top of the cantle may have a set stone, jewel, or emblems such as Saint Andrew, a thistle, Clan or Masonic symbols.

• "Military Sporrans" may be worn with regimental attire. Pipers will often wear the most flamboyant sporrans with long horsehair that swishes from side to side as the piper marches.

The sporran hangs just below the belt buckle; and much effort is made to match their style and design. The kilt belt buckle can be very ornate, and contain similar motifs to the sporran cantle and the Sgian Dubh.

When playing golf, driving a car, dancing or engaging in any activity where a heavy pouch might hurt, the wearer often turns the sporran and chain around the waist to let it hang on his hip in a more casual position.
