I made a button up shirt! I used the Grainline Archer pattern (all patterns are 20% off through Monday with the code GIVETHANKS20) and love it!
I cut a size 4 and used the 1/2 inch seam allowance everywhere except the side seams where I increased it to 5/8 inch. I'll probably still bring in the side to make it a bit more fitted. I didn't use the instructions provided with the pattern, but followed along on the Grainline Sew-a-long. I sewed most of the shirt in a few hours, but then the cuffs started confusing me, so I had to put it away until the next day.
I am a big fan and already have several other lengths of fabric designated for this pattern. The only thing I don't like about the pattern? Having to sew on soooo many buttons.
