Yeah, I wore them throughout the summer and the paint is wearing off in areas of stress and the red is showing through, just as I was hoping for. I didn't use "crackle" type paint so they don't crack like the MMM versions.
It's weird, it's been so long since these kinds of sizing questions have been asked here!
This has been discussed several times in the past, but it's hard to give a definitive answer because some people have longer/shorter torsos, shorter/longer legs, etc.
...but that's probably too short for 6'1", I'm 5'9" and Charly recommended 21" front length for me...
