Find sew pattern


I don’t know if this is off topic, but I want to find a “pattern”, you know, these shapes you have to cut out and sew together, for a button down shirt, but I don’t know how to search…

And haven’t really found anything useable so far.

Any suggestions would be greatly appreciated.

Technically it’s off topic because this is a knitting forum so it may have been better in the lounge…

Have you tried just searching for “sewing patterns”? The books I know of that have patterns in the fabric stores are McCalls, Simplicity and Vogue so looking up that may help, too.
