Classic Button Up Professional Work Vest #SJ1540 (M, DChar) Dark Charcoal

I am usually a small/XS. Based on reviews and availability, I purchased a M. It fits VERY snugly, and I'm positive that a Small would not have fit very well. It doesn't have a lot of give, so if you're larger busted or gutty, definitely size up. If you're tiny topped, maybe the sizing would be more as expected.I have another vest like this which has less buttons. I kinda prefer that, but I'll deal with what I got. In my experience, these vests tend to run small.
