There are higher things to dwell on. Crisp, high-quality white button-up for a higher-class affair. The collars are button-down for a clean look.
 
This item is meant to fit slightly large, so order a size down if you want an exact fit.
For example, if you normally wear a Large, order a Large for the kommpassion riot intended fit. If you would like it to fit you exactly, however, order a Medium.
