The Season
When choosing the perfume you are going to wear during the day, there are basically two important things. First of all, you should definitely choose your perfume according to the season. In my opinion, this is the most important one. For example, if you wear a winter fragrance in summer, it can become too much both for you and the people around you. I don't think anyone really wants to smell a sweet, heavy amber fragrance in the summer heat. Moreover, I would not really recommend it, but using summer fragrances in winter is not that unreasonable in terms of wearability, although of course you should not expect too much from them in terms of performance. Apart from some exceptions, you can usually wear winter fragrances in autumn and summer fragrances in spring.
The Environment
Second, you should choose your perfume according to the environment where you will spend most of your day. As I mentioned in the previous entry, if you are going to spend most of your day indoors, it would be better not to wear very powerful fragrances.
Other Factors
Apart from these two things, there are many other factors as well, such as your mood that day, the clothes you are wearing, and many other variables, but in my opinion, these are the two most important ones.
