I am a bigger guy in the mid section (working on that but thats another post altogether!). Button ups are usually hard to find in a good fit, but I have found one at a local store that was a faux style button up. It was a button up with a vest and tie, similar to the link below. I really liked it. It didn't add a lot of bulk to my frame and it looks great on me. I love the feel, fit, and style.
This is just an example I was able to find, same brand I bought actually though. But this is all one piece. Goes on like a tshirt.
Anyone have any ideas of places to look for these style tops? The faux, all in one type tops. Not necessarily just a vest, button up, tie combo. But a faux combo top?
