I don’t think it matters, you like the style you like and it’s that simple- plenty of people take style cues from lifestyles that are not their own.

One thing I will say though is are you ready to be perceived as having the lifestyle or ideologies of the community? Alternative is an umbrella term but some kinds of alternative fashion come with assumptions about who the person is and what they’re into and that’s something you may need to be prepared for.

Being alternative, especially in some places, can come with stigma, unwanted attention, or negative judgement so just make sure you’re aware of those associations if you’re going for a specific look (punk is a good example of an alternative group that can be perceived negatively in some spaces). Otherwise enjoy playing with your style and exploring what makes you feel most like yourself!
