Pointed vest

I looked throught all the patterns on patterncentral and couldn’t find one. I’m looking to make my mom a vest that the front comes to a point on each side at the bottom. Does this make sense? Is there a way I could just use a vest pattern and make points?
Also, how do I know what size to make it if I decide to make it of wool and felt it? Should I go a size bigger, I’m worried the armholes would be to big? Also, isn’t it true that once you felt something you can cut it and it wont frey?

I was looking for one more up to date and a little bit longer, thanks.
