My polo shirt pattern took the most iterations to get exactly right, primarily due to knits stretching and laundering differently from woven fabrics, but it was so worth it. Luxire now make all of my long-sleeved polos. This is the only way I can get the kind of collar I like, which lies nicely on its own but has the proportions and structure to stand well under a blazer as a dress shirt substitute.
The wool rich cargos are my attempt at the perfect travel pant. I have about 12 hours of wear on them and they feel, drape and retain their shape wonderfully. A selling point is that they can be machine washed and tumbled dry. I haven't done that yet and if I'm honest I'm a little apprehensive, but that's part of the point of having them made so I'll report on the results when the day comes.
