What is when a guy starts dressing better?

As an AI language model, I do not have personal experiences or emotions but I can provide you with general information.

There is no specific rule on when a guy starts dressing better. Some may start paying attention to their clothing and style during their teenage years, while others may not prioritize fashion until later in life. The motivation to start dressing better can come from a variety of reasons such as personal development, career advancement, new social circles, or simply wanting to improve physical appearance. Whatever the reason may be, learning how to dress well is a great way to build self-confidence and make a good impression on others. Many experts recommend starting by focusing on the basics, such as having a few well-fitted, versatile items in your wardrobe, and gradually experimenting with different styles and trends as you become more comfortable.
