I've made several pairs of these because they're the perfect weekend pants for me. I've dressed them up or down and worn them with a variety of tops and shoes. They seem cooler than a full length pant, but that could also be a function of the cottons and linens I've used.
Below are an illustration and technical drawing of the Hudson Pant from The Sewing Workshop website. It appears they're currently not in stock on the site but can still be found in stores or on the internet.
I don't have too much to say about the sewing. They're pretty basic pull on pants with the addition of narrow darts at the lower hem. One thing I like about the draft is that the back leg is angled at the waistband, so the crotch depth is added at center back, not all the way across. This avoids some of the "clown butt" look (thanks, Debbie Cook for that description!). I modified the pattern for me but started with a size Small, then added 5/8" at each of the outer leg seams. In my opinion, the pant runs a bit large so check the flat pattern measurements against yourself to check the size you'll need.
This pair is made from a linen and rayon blend that I got at a local ASG fabric sale several years ago. I was a bit meh about the fabric but it has a nice hand, so I figured it could at least be used for a muslin. However, I've come to like it as I've worked on the pants. I don't know if you'll see it again though. An entire ensemble would be too much of a good thing? Probably. The pants are more successful if a fabric with some drape is used vs. something stiff, even if you are using a heavy fabric.
It's important to mark the darts accurately and I've found that a Frixion pen is perfect for this. Only a tiny spot of ink is needed at each dot. Once pressed, the ink disappears! I've washed the pants since making them and the ink did not come back.
