Here is how to react and keep your sartorial cool when the sales assistant is the perfect bitch.. Because we´ve all been there at least once.
You take it from said rail and fondly imagine all those terrific parties you could wear it to, if you still had, you know, a waist and a life, until you feel the sales assistand breathing down your neck - literally. You turn around, and she snarls uninvited: "But this is a size 34, you know?" What would you do?
Well, if you are like me, you retort "Perfect!" with a radiant smile, take the dress to the fitting room, squeeze everything you have into it (she was wrong, though, it was a size 36), hold in your tummy until your face is turning a nice shade of blue, turn three times in front of the mirror (I couldn´t do more turns, I was already on the verge of fainting), pant out "What a bummer! Too loose..", then leave the dress lying around on the fitting room floor and leave the building as the moral victor.
I am quite sure one could solve those situations in a more grown-up manner, but I wouldn´t know how for the life of me. I should ask the kids one of these days.
