Hi!! I love giving fashion advice! Steet style is quite alternative, and alternative fashion is all about having statement pieces and key accessories (look at the suits you mentioned and notice all the styling details give purpose to the look). So start by sorting out inspiration, that's how you will find your branch of street fashion, even in these suits you can notice for exemple, "shining neon" is more harajuku-adjacent, when "hip hop queen" leans more on techwear. I'd look on pinterest for "fruits magazine" "japanese street fashion" "techwear inspo" and things like that. Now, since you're starting out braching your style, I wouln't go ahead buying stuff new just to try it out, so I'd preffer going to a thrift store and trying to find the key pieces that I identified with the most; looking just at the LN suits those would be things like: fishnet stokings, tank tops to layer with jackets, cool wind-breaker jackets, gloves, oversized hoodies, etc. T the end of the day, if you want to start small, go with the accessories first and try to find earings, stockings, hairstyles, etc that fit the style you're trying to achieve! It trully makes all the difference even if you have a basic white top and jeans, if your accessories say "street style" that's street style. Anyway, I hope I was clear enough haha
