After reading 13 pages of Vox's SwissArmySuit thread, which was quite strange, here is a summary of the suit he posted:
"Ha! Well, many of you guys had your imaginations unleashed, but everything that you imagined was awful in conception. Truly.
I made it quite obvious what my objectives were, but here is a recap.
1. Something that could be used for travel but that would cut down on what needed to be packed. Exactly what the BlazerSuit accomplishes. But, I was going for a wider spread between formality and informality.
2. The 13/14 oz fresco is a perfect traveling fabric. It resists wrinkling, and hangs out very well. Moreover, it's hopsack-y makeup is perfect for passing as a navy blazer.
3. I'm not as temperatures sensitive as many are, and can wear a wide variety of fabrics year round. The buggy lining can take this jacket into the summer for me...and the vest can take it into the winter.
4. With the vest, I have a bespoke-y looking suit that can be worn in social or work circumstances in which that is not an abrupt class challenge. I can even tuck the outpocket flaps in to make Mattypoo happy.
5. Without the vest, the suit can be a bit more CBD, especially without my usual ticket pocket. More politically mainstream...more lapel pin.
5. It's been a couple decades since I had a SB blazer with metal buttons. Now I have that, and I don't need to pack it seperately.
6. All the different button combinations are enough, for me at least, to alter the character of the suit or jacket in interesting ways.
The main construction challenge, which was not as simple as you might assume, was in keeping the precision of fit and avoiding buttons that flop around. There is also the issue of comfort in how the buttons are backed, and trying to maximize the durability of the transitional elements in daily use.
That's my story and I'm sticking to it."
