While it's normal for your fashion sense to evolve with time, picking out clothes is a very personal experience, and being pressured to dress a certain way based on your age or social circle can hamper honest expression.
It should go without saying that clothing has no gender, and anyone should wear whatever they want, so long as it makes them happy. Nonetheless, clothing marketed towards men tends to be more limited in style and color, while the ocean of clothes for women is often prescriptive based on age.
The immense pressure of beauty standards often urges young women to bare all in the sexiest ways, while punishing women over middle age for showing even an ankle. It's a gross double standard that shows just how fickle and disdainful our culture is towards female bodies, and how even the fashion industry views women's bodies as public property.
