"vest" of friends pair. I seriously love boys in vests. It is a great way for them to look hip and cool, and dressed up if desired. I love pairing vests with jeans for that "casual put together" look. As a total bonus my sweat pant loving little dude (seriously if he could he would live in sweat pants/pj's) When I asked him to change out of his sweats so we could take pictures his arrangement was that as soon as I was done he could put his sweats back on. I agreed, and then when he got dressed he told me that he liked it so much he didn't want to change. I won't go as far to say he wanted to wear it to bed, because let's face it, if he doesn't change into his spider-man pj's then the world would not be safe at night... but he loved it, so that made me happy.
Need help drafting a shirt? Here is what you would change:
Drop the under arm by about 1-2 inches (some nice wiggle room there)
Then the back is done cut 2 on the fold if you are lining.
Then for the front use the same piece only add 2 inches in width for the buttons.
Then add an angle in the front and an arrow like point at the bottom.
Done. Cut 4 not on fold.
Your pieces should look vest like if you did it right.
