Thanks for the feedback guys! Yes I did use body measures. I knew this was prone to errors so I also did a "smart size" at the same time as a point of reference. I was surprised that the smart size suggested measures even larger ( a 20'' midsection!) than the output from my own measures. I went through my other shirts (both tighter and looser) and took measures to determine which was "best". I had gone for a 19.25'' midsection but when I measured it, the shirt was at 19.75'' even though I had washed it 4 times to account for shrinkage. Based on my other shirts, an 18.75'' should be just right, slim without being overly tight. And yeah the collar is too large. Again comparing with other shirts, it's still 0.75'' too large even after shrinkage. I didn't have the collar stays in the picture because I had just ironed the shirt and I was certain of wanting to tighten the collar. My advice to anyone jumping in would be not to trust the smart sizes, or even your own body measures since those aren't the actual measures that go into making the shirt. Measuring your own shirts and seeing what works best will probably give you the best results.
