I actually think it might be cute belted or tucked in, so I'm not giving up on it forever, but I'm going to shelve it for a while and let it cook in my brain a bit before I try again. In the meantime, I thought I'd share with you all the alterations I made.
second edition of FFRP) to minimize the width of the bust dart. As you can hopefully see in the picture, you split the upper leg of the alteration in half, so rather than adding all the extra to the armhole area, you add some into the shoulder as well. Since I have rather narrow shoulders in front, this method isn't always ideal for me, but it works when the sleeve is cut on. I also added 4 inches to the length, as I like my tops long and this one barely comes past the high hip as drafted.
From the back it is a little easier to see how I added the sleeve. I just extended the shoulder line far enough to cover my shoulders, then added the 5/8 SA/HA and connected the end of the line with the underarm on the pattern. Easy peasy.
