You walked around, said yourself beautiful, just too bad they stare

I'm struggling with what to wear on the plane, jeans and a nice top are my nr. 1 option but as I look at the next week's weather forecast, seems like when I land, Montreal is suffering from 36 degree heatwave, I'll melt and I can't think of anything else than only bikini to wear in such heat, but how do evil custom officers react to ex-soviet girl in bikinis trying to enter Canada? I spy imaginary 'slut' written all over my forehead, um, correction, boobs, can't think of a reason anyone staring at my forehead. Anyways what the hell is up with this heatwave trend?I'm going to Canada (up north, snow, moose, Eskimos!!) for christ's sake not freaking Egypt!
