The other day, I set out for what I thought was your routine hot girl walk: I put on my gold hoops, my Supergoop sunscreen, and my Lululemon belt bag, and headed out the door with my dog. I was of course also wearing the HGW uniform — a matching set — although I’d layered on an oversize T-shirt on top of it.I didn’t see the green smoothie stain until several hours later. It must have dribbled onto my shirt many hours before because by the time I saw it, it had crusted over; I had to use my fingernail to scratch it off.
