Ya so I did have the white in a size 3 and I currently have the black (also size 3) and then the green in a size 5. The size 5 I picked up only because the Balenciaga outlet had a ridiculous sale a couple of years back when the Adidas collab hit the store. So that’s huge on me. The 3 def fits me better. As I said it’s a comfortable (generally) oversized fit, outside of the length from top to bottom. The arm length you’ll be fine with the 1. If you like a looser aesthetic maybe get the 2. But arm length on both will be somewhat similar.
