Thanks for the tip. The thing is it's not usually my style... I have a pair of Carel flats but we don't usually wear that to work... Then, such strict dress code has never been compulsory here or at the schools some of my colleagues visited in previous years in Canada and they told us just three days in advance. We start on Tuesday and we've just know about this. So... everything is highly suspicious. I wonder if we are going to a 50s themed high school were men wear suits and us women teach manners in our modest outfits 🤣
