A guitar strap I've personally been wearing on my telecaster for the past 6 years with a 1930's inspired floral embossing compete with a solid brass stamped roller buckle that can either go with just about anything or full on western. Lined with Full Grain Pig.
 
-To attain your guitar strap length measure center hole to hole on a current strap of yours. I'll make that the center hole of your new strap and give it a few holes in each direction for adjustment.
