Levy Suede Strap in Tan with suede backing. After the guitar cable the strap is the most important accessory you'll buy. Levy Straps are comfortable, rugged and come in a range of colors and styles. Cheap plasticy straps not only look awful but can be present a real danger of dropping your guitar. Youtube is full of videos of guitar strap failures and repair shops everywhere see guitars with broken necks and damaged bodies from strap breakages
Adjustable by seven lengths from 37" to 54" you can wear your guitar at 70's chest height or 90's grunge low. The tan leather would go great with natural wood and sunburst guitars, especially with tweed cases.
