There are many points for attention in thesis defense, which can be roughly divided into clothing, etiquette and thesis answer.

Clothing. First of all, it is not recommended that you wear formal clothes. Suits are indeed clothes that should be worn on formal occasions, but considering that you are a student, such clothes will give people a depressing feeling, because teachers are not too formal. Secondly, don't wear too many sexy clothes, especially girls. You said you were wearing sexy clothes. Does the teacher look at you? Therefore, I personally recommend leisure suit. Leisure suit is not only comfortable, but also not too casual. This will ease your mood a lot and will not affect your normal play.

Etiquette: There should be a lot of attention in this respect. I mainly talk about a few mistakes that most people make. First of all, when you go on stage, you should bow to the teacher who presides over the defense, and then bow to the audience and the defense teacher at a certain distance from the defense desk to show your attention. Then, don't look at the defense, don't make eye contact with the teacher, and judge your speech speed by the teacher's expression. You must slow down at once. Finally, when answering questions, if necessary, don't point your finger at the teacher, but use the invitation gesture.

Interpretation of the paper: When you are describing your paper, don't read it. Basically, you must delay the manuscript, otherwise it will give people the impression that your paper is not your own work, which will lead to a bad impression on the teacher. When asking questions, the questions may become difficult. Some unimportant things, such as materials, are taken away when mentioned. Don't spend too much time, but focus on the results of methods and data sources. The decisive factors can be listed in detail to highlight the reliability and professionalism of the paper.

To sum up, the thesis defense should basically pay attention to personal performance. Judging from your dress and attitude on the stage, you will feel relaxed if you take seriously the performance of etiquette on the stage. The interpretation and details of your paper are all points for you.
