Is any stretch likely in these? They're definitely a keeper as the next size up will almost certainly be too big, but they are quite snug on the waist and an extra cm would be ideal!

Good morning all......

Does anyone have any experience with the following Samurai unsanforized one-wash denim:

Am just wondering if I can expect any stretch at all in the waist on these, as I presume unsanforized one-wash will push back to non-wash measurements with pressure?

Thanks.

Any other colours coming in the oiled version?
