craftgrrl | vest/waistcoat help...

I am fairly new to sewing and am looking for a pattern (or at least some direction) to make a vest/waistcoat. I'm looking to do something pretty simple and somewhat fitted. I would prefer it to be something that could be worn both open or buttoned (though at this point I'm not going to be too picky). I wasn't able to locate a great picture to show you what I am looking to make, but I have seen them all over the place in H&M and F21. Has anyone tried a similar project and has some advice to share ? Or have any ideas for websites to checkout?

Thanks in advance... I've been going crazy trying to figure this out...

PS - What sites do you go to for clothing inspiration?
