I think that a thicker tie actually looks quite fine with thinner lapels. For example, a 3.25" lapel suit with a 3.5" tie. Since the 3.5" is really at the bottom of the tie and not visible when wearing the suit. The exposed area of the tie is then pretty darn close to the lapel width if that makes sense. Obviously this works best if the tie is only slightly larger than the lapel width.
