You gotta be kidding. I ordered a size 12-30.  I assume the 12 means Size 12, and the 30 is the inset. Well, the 30 part was right, but I could not get these jeans up past my knees!  The 14 size jeans I have in my closet are baggy and big, because I've lost weight, and other size 12 clothes now fit well.  But these jeans must have been the equivalent of a size 4!!  I called Amazon, and they didn't have a size chart and couldn't explain the problem. I searched the Calvin Klein URL and there was no clue as to what 12-30 for sizing would mean.  Nothing!!  So if you want Calvin Klein jeans, buy them in a store where you can try them on. I ended up going to Macy's and buying a different brand of jeans which were size 12's and fit great. By the way, Amazon was very accommodating and allowed me to send them back and promptly gave me a full refund.
