The orSlow Regular Fit Fatigue Pants in Black Stone is one of their most iconic styles that they carry and inspired from the classic military fatigue pant. The Regular Fit has a very moderate taper for a mostly straight cut through the legs, and an accommodating top block. The Black Stone Fatigue Pants are stonewashed for a worn and faded appearance. If you're looking for a slimmer cut through the legs, take a look at the Slim Fit Fatigue Pants in Black Stone.
While the following review is for the Slim Fit Fatigue Pants (not Regular Fit) in Green, you can get an idea of how the same fabric (different color/wash) wears and how sizing in general works with the waist tabs by checking our our 9 month review of the Slim Fit Fatigue Pants on the The Shade.
Note: Our sizes represent the tagged "Japan" size (not conversion to US sizes). Please review the measurements and additional information here. Due to the higher rise on the Regular Fit, you may not necessarily want to take the same size as you do in the Slim Fit Fatigue Pants (you could actually size down). We would generally equate the size 3 here with a size 32-34 in denim sizes; size 2 here with size 30-32; etc. Because of that, you will definitely be able to fit into a couple sizes depending on how you want them to fit. The adjustable tab will generally allow you to tighten the waist by up to 1" (when laid flat), or 2" in overall circumference. For example, size 3 had a waist of 17" when laid flat, and can go down to 16" with the button tab adjustments. The fabric does stretch a little over time by 0.5" when laid flat, so you can try to take that into account if you'd like, or just use the button tabs to tighten up as needed. Washing warm and machine dry will tighten up the fabric just a tad, but does not shrink the pants as they will stretch back out upon wear.
Model: 6'0'' and 175 lbs, with moderate "lifter" thighs, wearing size 2 for a relaxed fit where the waist is snug and good room through the legs. Model can also wear size 3, but the waist is a bit loose.
