I have a whole lot of shirt patterns.  I like most of them and have my favorites.  One pattern I like is Islander 228.  I have had it about 5 years and I first found this pattern through a Craftsy class.  Of course I purchased the class on sale and it included the pattern.  Now the pattern is separate.
It can be purchased here.  This is a download, but a tissue pattern is also available here.
I decided to sew this shirt in medium with my White 571.  I have had this machine 8 years, but haven't used it in a while.  If my memory is correct, I think I paid seven dollars for it.
I made the button holes with my Singer Professional Buttonholer.
I used my Singer Quantum Lock to serge the seams.
Here it is in a lightweight cotton blend I had in my stash:

| The tower packets are easy |
