I must say I was surprised by the quality of these jeans upon opening the package.  I have the size 16-Regular in black and they would be perfect for the average 10 - 15 year old girl depending on her height.  Girls will probably have to wear these jeans with a belt since the waist is not tapered in very much but the legs are nice and long.  Boys should have no problem at all with the waist. These jeans are already very soft and seem to be very well made with a strong metal zipper.

I haven't washed them yet and that will be the acid test if these jeans keep their 5 star rating.  I will definitely report back after they've been run through the washing machine and dryer, but upon first inspection they seem to be a good buy.

UPDATE: NOVEMBER 28, 2011:

I washed and dried the jeans and they did fine.  The legs remained straight, and I noticed that the inside of the pockets were made out of deep black material that matched the color of the pants.  Super soft too!
