I'm pretty sure adversarial fashion hoodies are something you would only wear if your aim was to stand out. Porch thieves just pull their cap low and look at the ground while nicking your package.
Granted, a hat will not trick "person" detection, you'll still get picked up in the box, but any camera that records with motion will still detect you in the adversarial pattern too as a person, even if it doesn't pick up your face to ID you.
If I were up to anything nefarious, I'd rather blend in with other humans as much as possible, not stand out like a sore thumb.
