Friends say you are old-fashioned. You can reserve your opinion that you don't want to waste time on dressing up, but you want to change after today's blow. I guess someone you care about must have said something like "old-fashioned" that made you feel uncomfortable. The person you care about may be a man or a woman you admire, or an idol you admire and respect. What kind of person are you?
On the other hand, thinking can improve one's ideological understanding and the depth and speed of one's understanding of things, but one should think more. People really care about each other's clothes. So in order to maintain interpersonal relationships, it is also appropriate to dress up a little. I think it should be enough to stay in a' non-conservative' state. You don't have to be glamorous, you don't have to cater to the trend, but at least you have your own taste and look like you like.
If you really find it annoying to dress yourself up, you might as well ask your friends to help you make suggestions, give N kinds of plans, and then make the final choice.
