putting the knit in shizknitz

I started seeing this phrase on BananaRepublic.com.  Is it that they are making the sizes larger or are people just skinnier?  To add insult to injury for us short pudgy people, Gap began making their Ankle (A) length pants about 2 inches longer in the last year.  So now I get to continue feeling good that I’m a size 8 but crappy that I’m getting shorter in my old age.  Not to mention that I have to keep taking my pants in to get hemmed.  Or, perhaps people are just getting taller in general and thus Gap decided to make their short length longer….. hrmm, a trend toward taller and skinnier people.  I get it - perhaps I’m not in their target market anymore.
