nuances wago-and-kango
Express that something is trendy with 流行
流行る【はやる】 and 流行する【りゅうこうする】 are a [wago-kango
pair](https://japanese.stackexchange.com/questions/tagged/wago-and-kango).
They are interchangeable in the context of fashion trends except that the
latter is a little stiffer. Both are used also in contexts of infectious
diseases (e.g., インフルエンザが流行る/流行する), but 流行する is preferred in serious academic
contexts.

流行る also means "(for a restaurant, etc) to be popoular". この店は流行っている simply
sounds to me like the restaurant is popular, but この店は流行している sounds like the
popularity is a temporary trend.

流行になっている and 流行している are almost the same, but the former expresses a (recent)
change in trends, whereas the latter expresses only the current situation. The
same is true regarding the difference between 流行りになっている and 流行っている, but I feel
流行りになっている is a bit uncommon.
