I've been getting pretty deep into pattern drafting

I'm going to level with you - I've found myself pretty deep into drafting my own sewing patterns.

It all started with commercial patterns. These are pre-made patterns from established designers and companies that are traditionally graded. The patterns come with a set of sizes, to make the garment in, for example, sizes XS-2XL.

But a lot of the commercial patterns available for men sit closer to the casual in the smart-casual spectrum. The more formal patterns don't go down to my size (28" waist, 34" chest). Funnily enough, this is one of the big reasons that I wanted to learn to make my own clothes: if I want high quality mens tailoring, then Custom Made (whatever that means) really is the only option I have.

If I want to just make (and not design) traditionally male garments, the only option I have is smart-casual patterns made to standard measurements.

In translating these patterns from their intended fit and cloth into something more suitable (pun intended) - I found myself quite unhappy with the things I had in front of me.

For example, I have chunky quads (from a decade of semi-religious commitment to road cycling). So I found seam allowances on the sides always pulling around to the front. But I have a pretty normal sized bum (or glutes, or seat, or hips depending on what we're calling it) - so adding cloth in to the legs caused a lot of droop just under my butt-smile. Do I want a garment that makes me look droopy?

At this point I start thinking "well really how hard can it be?".

Smash cut forwards a month, I am using Seamly2D, an open-source CAD software for fashion design, and the Aldrich system for drafting mens' garments. This is one of legitimately two-to-three formalised systems for drafting the handful of traditionally male garments.

Side note: why can't we have fun, or at least varied, garments?

But the system for drafting garments gives you only a few of the basic blocks for building e.g. trousers. What about built-in vs. Separate fly pieces, or welts and pocket facing? Now I'm having to reverse engineer individual pieces of cloth to fit the custom garment.

It's sort of like yak-shaving, but I'm pretty certain that all the steps along the way are necessary. Or at least, the least bad option.
