First post–hello, all!

I'm one of the aforementioned slimsters (height: about 5'8", weight: 125 lbs.) who's been eyeing the last pair of olive pants, but I'm not quite sold on the sizing--primarily, the waistband; the rest of the top block seems like it would fit me just fine, if maybe a wee bit tight, but that's what stretching.  Hearing that it should be a size up from normal has me a little nervous about pulling the trigger, as I'm not sure the waist would stretch enough to make this a comfortable fit.  Which is a shame, because I'd love to have a pair of these tapered slim.

For reference, I'm currently rocking a pair of the Naked & Famous Elephant 4's in the Weird Guy fit--and I probably could have used the Skinny Guy fit instead; these have plenty of room as is.  Given that, is there a possibility that these could be stretched enough in the waist to make a snug fit?
