I only wear 501’s and I think this is the answer. Depending on where they are made determines how well they fit. Long ago, they were made in the USA and they were pretty consistant. Now, they come from all over and vary quite a bit. (They also do not last as long, by a huge margin)
It also depends on how you “break them in”. The old ones would shrink-to-fit in a predictable way. Now, its a guess.
Now, I buy used ones from the thrift stores for about $5 (because they don’t last for shit now). I ain’t shellin’ out $35 for an “inferior” product.
By the way, you are all SHORT and SKINNY!
