For wearing a sporran you have three choices.

1) chain - commonly seen and sold with many sporrans. I wouldn't recommend it for regular wear, as it will abrade the material on your kilt quite quickly.

2) strap - a thin leather belt that replaces the chain and "d-strap" (the small leather strap with two d-rings that may reside in your sporrans strap-keeper when you get it).
A sporran strap is much more comfortable than a chain, and if it's well made (finished back and edges) will not cause damage to your kilt.

3) hangers - you may or may not come across these in the UK, but they are two straps that hang off your kilt belt (more properly known as a dirk belt). They attach to the d-strap like your chain would. Commonly seen on gentleman of substance in the US, as this way the sporran doesn't ride below the belly.

Of all the options, the simple strap gets my vote, and isn't difficult to find.
