yours are the linen covered augustas? there might not be enough contrast between the texture of the linen and denim to look right.
for me it is still mostly denim on off duty days, but rarely indigo. Usually grey, black, white. I have dark navy nylon biker pants and wool drawstring pants that I am trying to work into the rotation, but I havent tried them with my augustas.
The challenge with denim for me is that it is sort of a thick fabric to tuck into boots. sometimes it works for me and sometimes not.
my oiled augustas are sort of wasted unless they are tucked, therein lies the conundrum.
