I unfortunately couldn't find your pattern. I found quite a few that don't have the same pretty lace, but may have the same vibe you're going for. I found these by looking for 'mesh crochet cardigan pattern' on google and going down the rabbit hole of related photos. I don't know if 'mesh' is the right keyword exactly. You may like the look of filet also. I spend way too much time on this lol, but came across some things that I would also like to make :) Hope this gives you some inspiration at least.
