What fit of 21 oz are they? you can try leaving them stretched for a week or more. Otherwise, you might have to sell them off and get a pair in a better size
For what its worth people telling you to size 1 or 2 down in these jeans are either stick figures or masochists, theres no way anyone with even a remotely athletic physique can fit into sized down tapered, let alone skinny.
My 33 grey tapered came in last night and they fit wonderfully. I can button them and they are snug and perfect. Loosening shouldnt be an issue, the thighs are slim without being skin tight like a sausage casing. Ill post fit pics
BTW the chambray shirts are awesome. They are definitely slim fit though, I got a large and I can easily fill it out by flaring my back, it fits nicely though. I picked up a red, considering the indigo one as well. Definitely a good shirt that will last a long, long time (be advised its prob a fairly warm shirt)
