Create a pioneer shirt out of a regular white dress shirt.
With just a few quick changes, a white dress shirt can appear more like a pioneer shirt. Secondhand stores are great places to purchase shirts.
The shirt you use needs to have a two-piece collar— a stand and a collar
First, remove the collar from the stand by removing the stitches that hold the collar in place.
Next, remove the pocket by unpicking the stitches that hold it in place.
Finally, pin the open edges of the stand together and stitch them closed.
You now have a shirt that resembles a pioneer shirt.
