Tata Harper Aromatic Irritability Treatment, $65, tataharper​skincare.com

This went straight into my bag. As anything claiming to ameliorate (or even mitigate, slightly) irritability would. It’s this vial of organic aromatic oils; you roll a bit in each palm, cup your hands over your face and inhale. I did this in traffic on a very ugly highway in Brooklyn, and it worked. Once out of the traffic, I arrived calm, cool, even good-natured—everyone asked me what gorgeous perfume I was wearing.
