Spier and Mackay Shirt Sizing

Hello, about to buy a few shirts and am a bit concerned after reading that Spier & Mackay tends to be smaller than people expected. I measured myself at 37" chest, 34" sleeve. 5' 9" 155 for reference. I also have a dress shirt from Calvin Klein which is a 15 slim which I think fits well. I'm planning on ordering 15 contemporary, can I get a sanity check on that? Would 15 slim be too small? Here is their fit guide https://www.spierandmackay.com/fit-guide/size-chart-sportshirts

Look closely at the measurements, but also some of them shrink more than others. Mine haven't been too bad and have only shrunken by half an inch, but I've heard some horror stories.
