I think we are at a phase where we are back to something like the 1960s, which was itself a kind of return of the fashion cycle to that of the Edwardian era. Both the Edwardian era and the 1960s were peaks in stylishness as far the 20th century went. Clean fits and narrower lapels were the order of the day in both periods. Let's hope this decade can make the most of it.
Hope this is true and sticks around for a while.
People who say that mid width lapels are correct- bah humbug. All lapels are good. The ones I like the most are the widest.
