Ties are a fun way to express your personal style
You can build an empire of ties because millions of different colors, patters and textures exist. But don't be overwhelmed. Quality over quantity can be a winner in this case, like (almost) always. Try getting ones that are between 2"-3" wide. It'd be good to match the tie width to your suit lapel width, but being within .5" should be okay. Just don't wear a super skinny tie with a wide lapel suit, okay?
If you want versatility, then you may want to start with a 2.5" solid navy blue or charcoal tie. Navy will go with almost every suit except black, which you shouldn't be wearing too often anyway. And charcoal can go well with anything. There's a reason why these are also the basic suits to start with as well. These colors can just be mixed and matched in versatile ways, but also safe ways if you aren't into taking too many style chances.
Moreover, actually tying the tie well is probably more important than how stylish it is. You may already have your muscle memory programmed to tie it a certain way, so if what you do works for you, then do you sir. For those who seem to tie it a different way each time or can't figure out how to keep the tie from falling well past your belt, I'll share with you my go-to method for tying it together:
