I’ve done a side-by-side comparison of this blazer with removable collar to the Veronica Beard Scuba blazer and they are identical in fabrication measurement, and designed details. The only difference is this blazer is not size numerically so you get less of an exact fit than you do with number sizing AND it’s about $600 less! I am 5 foot four, size 32 a or extra small and wearing an extra small with the removable zip in Dickie also linked here
