What are size do I need to buy Levi’s 501 shrink to ft men’s ?

What are the 501 Levi's going for how much

If your waist size is 36 and inseam is 32 ... you buy the next size up .. 38 waist .. 34 inseam in length .. wash them twice in hot wash with whites b4 wearing. Now ... if you buy the 501 Levi (Raw Denim) never been washed while manufactured .. buy your body size and never wash [Dry Clean Only] I've only bought Levi's for over 50 years. I have 20 pairs of Levi in different colors, styles of denim .. some are 20 years old with faded to paper thin.
