Probably because the waist is elastic and will stretch a few inches. That's my guess, at least.

A couple of the "regular" Bedfords are now up at Ind-Chicago, along with some other stuff:
I apologize if this is the wrong place to post this, but I was wondering if I might be able to get some fit advice if possible? First time purchasing/trying on a Bedford Jacket (ripstop olive from SS '14), and just wanted to see general thoughts on if this is a good fit, or if I would be better suited with a size down, since I'm not sure what the "ideal" fit of EG attire should be. Randomly threw together some clothes to try on with it. I am wearing a size Small in the pictures, buttoned and unbuttoned. I typically wear XS, very occasionally Small, with jackets, am 5'7"-5'8", 135 lbs, with a 35 inch chest measured around and approximately 17 inches shoulder width. With the jacket, the shoulders fit comfortably well, but the chest has a fair bit amount of room to give. Would appreciate the help!
