Mensusa Two Button Suits
Based on your height and waist size, you should look attractive in either a 2-button or 3-button suit. 3-button suit will end up having the V-point of your collars to be higher part of your chest. Mensusa 2-button suit includes length for your chest since the V-point is too lower. So any man with a short chest would benefit from 2-button suit. Seriously it is everyone’s best choice. It would be good for you to try it out and see the difference it makes to your overall look like massive.
Mensusa Double Breasted Suits
Double breasted creates an extra formal look. So you must know the purpose of your Mensusa suit. For work wise, single breasted and double breasted works okay. If you want flexibility where you can wear your shirt without tie, then the single breasted would be a best choice. But personally never find it as classy wearing without a tie with a double breasted suit.
Your choice of button should depend on the style you want to make. Usually the best choice natural horn buttons or higher quality ones are mother-of-pearl. For the most formal style, it would be clothed buttons where it matches precisely against your suit.
