I'm PM but fly pretty much exclusively coach as most of my flights are TATL and I can't afford to buy upgradeable tickets (so I'm thinking of putting my PMUs to some good use, maybe as drinks coasters). On a recent flight I was mistaken for a FA, as I was wearing a dark dress and cardigan, with knee-high boots. Earlier in the flight one of FAs had actually commented on my dress (which is very, very comfortable, as it's a bit stretchy and has no waistband).

So maybe the question is "What do Economy Class pax look like?"
