Thanks for the review. Realistically, almost all Poplin wrinkles easily and is slightly sheer. I'll report back on the G&R 2/140s soon, but my Alumo Supraluxe shirts all crease significantly throughout the day. However, I do have a sample of Alumo Soyella 2/170s, which I believe is a voile, and the sample is showing crease resistance.
Any suggestions on a solid dressier white fabric?
