There are many identifiers of a custom suit; impeccable fit, unique fabric, functioning buttonholes on the cuff, and so on. Yet, it is in the finer details for which we can truly distinguish an undeniably unique suit.
One of the predominant characteristics is that of the handmade buttonholes. Found on all bespoke suits, few custom suits and even fewer off the rack suits (only Kiton, Lardini and Tom Ford stretch their manufacturing to this fine, subtle detail). The pinnacle of this is the Milanese boutonniere on the lapel of the jacket – a mark of fundamental tailoring beauty.
