Too long
Size: 32W x 34L, Color: Vintage Blue
The jeans are multiple inches longer than they should be for the size and they are very baggy around the crotch. They are medium comfortable.

Superb value in a quality Jean! 10/5 stars
Size: 35W x 30L, Color: Rinse
35x30 is perfect sizing for me so the suggested size is true to life as I wear that size in most Jean brands. These are quality jeans, not the thin cheap jeans that I was expecting them to be but rather nice thick denim with quality stitching. They are very comfortable and look nice! I will most definitely be buying more. Way to go Amazon in providing a high quality product to your customers at a more than fair price!
