My school requires Dickies uniform pants, and these are my favorite of the various fits.  My child is very, very thin and I like that I can actually reduce the waist slimmer than the "slim fit" regular flat front pants.  Uncinched, the waist is only about .5" larger than the slim fits.  Therefore, if your child is on the larger side, I would definitely look into the "husky" fits (even for children that are not traditionally considered husky).  I would say that these are also on the short side.  I have compared the regular flat front pant side by side, and these are .5" shorter in the same size.  Therefore, size up if you haven't used these before or are in doubt.

Fabric wise, they are very tough and I love the reinforced knees.  The knee reinforcements don't seem to pull off like some brands might.  They wash well, and soften up over time (initially they come VERY stiff).  No fading, and stains release well.

Finally, I love the style (for a uniform pant).  The little kids look stinking cute in these pants!  Amazon has the best price I have seen anywhere, and FAR better than the "official" uniform store.
