You may be more familiar with yokes than you think. Front yokes are common to Western style dress shirts, though they’re not to be confused with the back yoke which is what we’re talking about here.
There are two main types of back yokes: a plain back yoke, and a split back yoke. The difference is between them is whether they’re made from one piece of fabric (plain) or two pieces – each from the center line to the shoulder blade (split). We favor plain back yokes here at J.J. Threads, but are happy to accommodate your preferences. If you’re so inclined, please feel free to email us at SOS@JJThreads.com to request a split back yoke.
