Im interested in buying a pair off the levis on-line store, but am a bit worried about sizing. They say to go up 2 sizes in the waist and that they will shrink 3-4 inches in length. I dont want to buy a pair knowing that they will shrink to nothing when i wash them. I usually go two sizes down in most dry denim and dont wash for about six months but i want to wash these and get a nice close fit, any suggestions? If anyone has these and can share any info on shrinkage and fit that would be great?
