If there was one non-fashion related art form whose artists inspire fashion the most, I think it would be music. When you think about any musical genre, you can probably imagine an outfit that any person within that genre would wear. Country music has the cowboy hats and boots, heavy metal has the ripped up jeans and studded leather everything, hip hop has the baggy jeans and high top sneakers, and so on and so forth. There are obviously exceptions to each of these styles, but the stereotype is there, and it is fairly accurate. Though it isn't really the music that influences the style, but actually the musicians making the music.
Personally, I like a few different genres of music. Whenever I am enjoying one genre more than the others, my style actually changes. For example, I am really liking alternative rock lately. My style has consisted of a lot of black and white, skinny jeans, and leather jackets and boots. When you look at pictures of a lot of the bands in that genre that I listen to, a majority of the members will be wearing something much like this. I also like indie folk, and whenever I am listening to that genre more, I start wearing more earthy tones, and lean more towards an Americana style with lots of denim, flannel, and boots. Once again, most of the members of those bands have a very similar style. The musicians in either of these genres definitely inspire me when it comes to my style choices.
In my outfit above I am wearing a t-shirt for the band Sir Sly, an alternative rock/indie pop band that I enjoy listening to a lot. Another way that musicians influence their fans styles is through band tees, whose graphics are usually reminiscent of the style associated with their musical genre.
However, over the years there have been a few musicians who have ascended their personal music fanbase and influenced the entire fashion world. Nowadays, one major fashion icon would be Kanye West. I don't much like a lot of his music, but his fashion sense is very unique and I like a lot of what he wears. Denim jeans with a lot of stacking at the cuffs (a less extreme example would be what my jeans are doing above), oversized sweaters, and white sneakers are all things that are in fashion right now, and Kanye is partially to thank for it.
There is no denying that musicians do influence fashion and the styles of their fans, but how much you let them is up to you. Just make sure you aren't idolizing the musicians and trying to emulate their styles perfectly. Be yourself, and take your inspiration from other things as well. In the future I will be talking about some other art forms that inspire my fashion choices.
