Don't come to class half naked. 不要穿暴露的衣服去上课

This may be appreciated by some of the male students (and professors too, sadly), but this is not the way to be taken seriously in the classroom. Save the sexy stuff for the weekends, and come to class looking a little more professional. Even outside the classroom, it can be sexier to leave a little to the imagination and show off just one feature at a time. If you wear a navel-baring shirt, wear baggy pants. If you wear a micro-mini skirt, pair it with a big sweater.
一些男同学可能会喜欢这样（很遗憾的是有些教授也喜欢），但这绝不表示你需要穿这种衣服去上课。性感的衣服还是留在周末穿吧，上课还是穿得比较正式点好。即使在课堂之外，穿得稍微检点一点，留给别人想象的空间，可能要比近乎半裸更性感。如果你穿件露脐装，就搭件宽松的裤子；而穿小迷你裙的时候就可以用松垮的毛衣来搭配。
