Good makeup
I came to this thread to argue with you, but actually, I agree. Although in addition to that I would advise a good hair style https://therighthairstyles.com/30-respectable-yet-modern-hairstyles-for-women-over-50/ as it will visually improve the appearance and hide some imperfections, exactly like make-up and clothes.
It is easy! You have Internet, I am sure, so you can get information about it in the Internet. Personally I would like to recommend you to read articles about makeup from https://joy-pup.com/en/health-beauty-en/how-to-visually-reduce-the-nose-size/ . I think it can be really useful for you!
