I don’t generally like peak lapels on single-breasted suits. They aren’t necessarily wrong – although notch lapels are far more common, only the relatively inexperienced will tell you it is a ‘rule’ that SBs must have notch lapels (or indeed black tie have peak lapels). Have a look back through some 1930s stills or films and you will find plenty of evidence to the contrary.
But peak lapels, for me, often look short and stubby on a single-breasted jacket. More like little bat wings than long, elegant fins. On a double-breasted, the crossover allows the lapel a crucial few inches more, echoing the smart military style of a sash or cross-belt.
The image of Gary Cooper above I think illustrates the point. Part of the problem is that these old suits had a higher buttoning point – where the waist button, the top of a two-button suit, fastens. They were cut with that point on the natural waist, just below the ribs, where the trousers also sat. That leaves less room for lapel.
The only way to save a peak-lapel SB design, then, is to lower that buttoning point as much as possible. They tend to be a good couple of inches lower on high-street suits today, but bespoke tailors will often retain a high waist button, even if the trousers are cut rather lower. The proportions of the jacket, after all, are still mostly derived from the same system of cutting that was developed for the hunting coat, which buttoned high and cut away sharply to allow it to be worn closed while mounted.
High-street retailers still retain a high buttoning point sometimes, as shown in the Reiss suit opposite. But below, you can see the difference of just an inch or so, in an Armani suit being worn by Kobe Bryant. And it’s no coincidence that peak lapels were often cut for more formal, three-piece suits like the grey Bryant wears. As these may have been worn open more often, the lapel has rather more freedom.
Finally Gianluca Bocache, of the shop Sartoria Ripense in Rome, shows how the buttoning point can work well in a custom-made suit. I repeat that I don’t like peak lapels and I still think this would look better as a notch, but if you’re going to do it, then give the lapel a little more length.
