Update on the Wool & Prince shirt... very nice - crisp and professional. This all-white shirt is half wool, half synthetic. It doesn't feel stretchy, it's quite conventional in that way. The care instructions are a bit troubling: "Let the wool do the work. Dry clean only." Not sure if they imply multiple wearings are possible due to wool odor-resistance? Worried what self-laundering in a hotel sink might do to this shirt. But, it looks great. And, there's a pocket. I'll experiment with it... what's the worst that could happen?
