'Tis true, how you look changes people's opinion towards you. I wore this pretty wrap top with jeans to school one day and I found people were looking at me and smiling all day. Even people who I know dislike me smiled when I passed them. Whereas when I decide that I don't care how I look and go in wearing very baggy dark green trousers with a pinky/red top and a white strappy top underneath and look absolutely rubbish, people star at me like I'm absolute trash, just because I couldn't be bothered to look decent for a school day at my all girls school!!!!
Its the same in shops, I went into Esprit once, wearing a strippy pink top (not particularly nice looking one) and jeans, the looks I got from them were digusting. We're a really critical bunch of people over here.
