NWT We The Free Americana Jacket

NWT amazing whitewash denim with frayed hem patchwork on chest. Size 0. But I’m typically a 4 and it fits me. I did notice some small dots in the left side of the collar (see 3rd pic). I’m not sure what they are as I’ve never worn it. Approximate measurements: Pit to pit 16” Arm length 23.5” Please let me know if you have any questions!!
