Though no hidden rivets so probably the cone version for sure?
The Slim Straight is the cone denim that's on sale and was on sale last season for $159 too.
Slim Fit Japanese almost never goes on sale. Maybe once in a while like 2 years ago it was included and I recall a bunch of people ordered it using someone's private sale code and they cancelled most of the orders. I think certain stores put the left over scraps on sale every once in a while before the new stock comes in but now that this should be the last batch they're probably going to keep them until they sell for MSRP.
My kingdom for a bike.
Enough already, just buy all the sizes you think you'd might fit into and return what doesn't work. They have a great returns policy.
