Sent a chat but I’m interested in the jacket

Anyone have any good sizing advice for these? do they shrink/stretch? I thought I was a 34, but comparing the size chart to the Oni's 622 I've been wearing is making me consider a 33 (and I found a 33 in stock). Am I going to regret the 33?

Hoping these will get a restock/rerun soon! Been calling my name lately and I can’t find a 34 anywhere
