There is a multitude of different factors that will impact the clothing choices that people would end up making at the end of the day. Some of these factors would have to do with aesthetics which makes a lot of sense when you consider that clothing can be a powerful way to express who you are deep down inside, and it can enable you to find people that conform to your own aesthetic philosophy as well because they would be rather easily visible to you if you go out looking for them.
However, many of the other factors that end up determining what clothes people wear and why are more closely associated with practical considerations. For example, if you are about to buy leggings from Niyama Sol, you might be doing so because of how they look but chances are that other benefits would come into play as well. One of these practical benefits is that leggings can help you stay really warm if you wear them under your regular pants. Leggings can also allow you to wear skirts when the weather is incredibly cold, and that is something that widen your range of potential outfits instead of having them be limited by things like the weather.
The benefits of leggings go far beyond this as well, including things like their level of comfort as well as how they can be used in both casual as well as formal settings. All of these things matter, and you should take them into account when you are looking for a pair that would be most suited to your interests because they can help you find better qualities ones for the most part.
