Commission of Solas,
The collar fabric came from the same manufacturer as the sweater fabric so it matches perfectly, but it was very (very) thick. The collar is lined in the 4x2 because self lining it would have been too bulky. I also extended the brown faux leather trim to just below the seam rather than stopping right at the seam so I could get the rivet in. I went through a number of drafts and tweaks of that collar shape and I'm happy with what I ended up with, but it took me a little while to get there. Knit is not the most cooperative fabric when it comes to trying to shape it like this. I tested out various angles of rise and height, interfacing/internal structure...
The seam around the collar and around the cuffs is accented with a hand stitch, and the brown trim is one piece, no seams. Water soluble basting tape (both to turn under the edges and to hold it in place for sewing) was indispensable for this.
The pants are a linen blend, pieced and accented with a hand stitch and faux leather lacing. Not sure what's up with all those seams, but that is how they're designed.
I purchased an extra long belt on etsy and stitched on the accents by hand. They're the washers from black grommets.
The shoes are made from sueded knit backed with cotton rib knit to add dimension (the suede knit is thin, and backing it made it look a little more like woven straps) and self-lined in knit. They pull on like socks and have some elastic built into the lining to help them stay up. I attached a 6 mm shoe sole so they can be worn outside or on concrete. The toeless style is not the most comfortable shoe design ever, but sanding down the front of the sole made them a little easier to walk in and stand on.
