Note to *GQ* readers: think twice before following the advice on three-piece suits in the January issue too closely. While we’re all for the return of vested interests, proper tailoring is absolutely essential when it comes to adding the extra element. You do not want your shirt and tie peeking out between the vest and trousers, and nor should your waistband be on public view, as has happened to *GQ*’s unfortunate model pictured here. Without a smooth, uninterrupted vest-to-trouser transition, “the entire elegance of a three-piece suit is destroyed,” as the great Alan Flusser notes. For this reason, low-slung pants, as on display in *GQ*, do not work on a three-piece, and belt loops have no place here either; side tabs are preferable, and braces are of course the classic choice.
