This is my first pair of skinny jeans and usually have the hardest time with jeans, so I went way out on  a limb by buying these online without trying them on.  I have a bigger rear and longer legs, I'm about 5'8" but I got them in the regular size and they fit everywhere so well!  I love them so much, perfect amount of stretch...just fabulous.  I came back on today to pick out another pair or two!

Still have the jeans!  Could have updated this review a long time ago as I've had these same feelings about them for quite a while...  They are just too stretchy.  After having them a while, I now NEED to wear a belt and even then they are too baggy everywhere else. I don't like having to wear a belt, so if they weren't so baggy elsewhere I would have given them 4 stars.
