Type IV – The Commodore, a double-breast jacket is unlike its ceremonial, more formal cousin, ‘the-six-buttoner’, it comes with four buttons that work, four x four. Supremely elegant, it is slightly shorter than average, it is slim sleeved, nipped waist and hipped and is truer to the original and more practical naval double-breast. The overall design allows it greater styling possibilities for what otherwise can be a difficult style to wear casually however, this jacket successfully achieves that effect. It has a curved military sleeve with a clean ‘blind’ cuff. This jacket can also be shortened or lengthened.
